 # Memory analysis
+The PineTime is equipped with the following memories:
+ - The internal RAM : **64KB**
+ - The internal Flash : **512KB**
+ - The external (SPI) Flash : **4MB**
+
+Note that the NRF52832 cannot execute code stored in the external flash : we need to store the whole firmware in the internal flash memory, and use the external one to store graphicals assets, fonts...
+
+This document describes how the RAM and Flash memories are used in InfiniTime and how to analyze and monitor their usage. It was written in the context of [this memory analysis effort](https://github.com/JF002/InfiniTime/issues/313).
+
+## Code sections
+A binary is composed of multiple sections. Most of the time, these sections are : .text, .rodata, .data and .bss but more sections can be defined in the linker script.
+
+Here is a small description of these sections and where they end up in memory:
+
+ - **TEXT** = code (FLASH)
+ - **RODATA** = constants (FLASH)
+ - **DATA** = initialized variables (FLASH + RAM)
+ - **BSS** = uninitialized variables (RAM)
+
+
+## Internal FLASH
+The internal flash memory stores the whole firmware: code, variable that are not default-initialized, constants...
+
+The content of the flash memory can be easily analyzed thanks to the MAP file generated by the compiler. This file lists all the symbols from the program along with their size and location (section and addresses) in RAM and FLASH.
+
+![Map file](./memoryAnalysis/mapfile.png)
+
+As you can see on the picture above, this file contains a lot of information and is not easily readable by a human being. Fortunately, you can easily find tools that parse and display the content of the MAP file in a more understandable way.
+
+In this analysis, I used [Linkermapviz](https://github.com/PromyLOPh/linkermapviz).
+
+### Linkermapviz
+
+[Linkermapviz](https://github.com/PromyLOPh/linkermapviz) parses the MAP file and displays its content in a graphical way into an HTML page:
+
+![linkermapviz](./memoryAnalysis/linkermapviz.png)
+
+Using this tool, you can easily see the size of each symbol relative to the other one, and check what is using most of the space,...
+
+Also, as Linkermapviz is written in Python, you can easily modify it to adapt it to your firmware, export data in another format,... For example, [I modified it to parse the contents of the MAP file and export it in a CSV file](https://github.com/JF002/InfiniTime/issues/313#issuecomment-842338620). I could later on open this file in LibreOffice Calc and use sort/filter functionality to search for specific symbols in specific files...
+
+### Puncover
+[Puncover](https://github.com/HBehrens/puncover) is another useful tools that analyses the binary file generated by the compiler (the .out file that contains all debug information). It provides valuable information about the symbols (data and code): name, position, size, max stack of each functions, callers, callees...
+![Puncover](./memoryAnalysis/puncover.png)
+
+Puncover is really easy to install:
+
+ - clone the repo and cd into the cloned directory
+ - setup a venv
+    - `python -m virtualenv venv` 
+    - `source venv/bin/activate`
+ - Install : `pip install .`
+ - Run : `puncover --gcc_tools_base=/path/to/gcc-arm-none-eabi-9-2020-q2-update/bin/arm-none-eabi- --elf_file /path/to/build/directory/src/pinetime-app-1.1.0.out --src_root /path/to/sources --build_dir /path/to/build/directory`
+     - Replace
+         * `/path/to/gcc-arm-none-eabi-9-2020-q2-update/bin` with the path to your gcc-arm-none-eabi toolchain
+         * `/path/to/build/directory/src/pinetime-app-1.1.0.out` with the path to the binary generated by GCC (.out file)
+         * `/path/to/sources` with the path to the root folder of the sources (checkout directory)
+        * `/path/to/build/directory` with the path to the build directory
+ - Launch a browser at http://localhost:5000/
+
+### Analysis
+Using the MAP file and tools, we can easily see what symbols are using most of the FLASH memory space. In this case, with no surprise, fonts and graphics are the biggest flash space consumer.
+
+![Puncover](./memoryAnalysis/puncover-all-symbols.png)
+
+This way, you can easily check what needs to be optimized : we should find a way to store big static data (like fonts and graphics) in the external flash memory, for example.
+
+It's always a good idea to check the flash memory space when working on the project : this way, you can easily check that your developments are using a reasonable amount of space.

+
+## RAM
+RAM memory contains all the data that can be modified at run-time: variables, stack, heap...
+
+### Data
+RAM memory can be *statically* allocated, meaning that the size and position of the data are known at compile-time:
+
+You can easily analyze the memory used by variables declared in the global scope using the MAP. You'll find them in the .BSS or .DATA sections. Linkermapviz and Puncover can be used to analyze their memory usage.
+
+Variables declared in the scope of a function will be allocated on the stack. It means that the stack usage will vary according to the state of the program, and cannot be easily analyzed at compile time.
+```
+uint8_t buffer[1024] 
+
+int main() {
+ int a; 
+}
+```
+
+#### Analysis
+In Infinitime 1.1, the biggest buffers are the buffers allocated for LVGL (14KB) and the one for FreeRTOS (16KB). Nimble also allocated 9KB of RAM. 
+
+### Stack
+The stack will be used for everything except tasks, which have their own stack allocated by FreeRTOS. The stack is 8192B and is allocated in the [linker script](https://github.com/JF002/InfiniTime/blob/develop/nrf_common.ld#L148).
+An easy way to monitor its usage is by filling the section with a known pattern at boot time, then use the firmware and dump the memory. You can then check the maximum stack usage by checking the address from the beginning of the stack that were overwritten.
+
+#### Fill the stack section by a known pattern:
+Edit <NRFSDK>/modules/nrfx/mdk/gcc_startup_nrf52.S and add the following code after the copy of the data from read only memory to RAM at around line 243:
+
+```
+/* Loop to copy data from read only memory to RAM.
+ * The ranges of copy from/to are specified by following symbols:
+ *      __etext: LMA of start of the section to copy from. Usually end of text
+ *      __data_start__: VMA of start of the section to copy to.
+ *      __bss_start__: VMA of end of the section to copy to. Normally __data_end__ is used, but by using __bss_start__
+ *                    the user can add their own initialized data section before BSS section with the INTERT AFTER command.
+ *
+ * All addresses must be aligned to 4 bytes boundary.
+ */
+    ldr r1, =__etext
+    ldr r2, =__data_start__
+    ldr r3, =__bss_start__
+
+    subs r3, r3, r2
+    ble .L_loop1_done
+
+.L_loop1:
+    subs r3, r3, #4
+    ldr r0, [r1,r3]
+    str r0, [r2,r3]
+    bgt .L_loop1
+
+.L_loop1_done:
+
+
+/* Add this code to fill the stack section with 0xFFEEDDBB */
+ldr     r0, =__StackLimit
+    ldr     r1, =8192
+ldr     r2, =0xFFEEDDBB
+.L_fill:
+str     r2, [r0]
+adds    r0, 4
+subs    r1, 4
+bne     .L_fill
+/* -- */
+```
+
+#### Dump RAM memory and check usage
+Dumping the content of the ram is easy using JLink debugger and `nrfjprog`:
+
+```
+nrfjprog --readram ram.bin
+```
+
+You can then display the file using objdump:
+
+```
+hexdump ram.bin -v  | less
+```
+
+The stack is positionned at the end of the RAM -> 0xFFFF. Its size is 8192 bytes, so the end of the stack is at 0xE000.
+On the following dump, the maximum stack usage is 520 bytes (0xFFFF - 0xFDF8):

+
+#### Analysis 
+According to my experimentations, we don't use the stack that much, and 8192 bytes is probably way too big for InfiniTime!
+
+#### Links

+
+### Heap
+The heap is declared in the [linker script](https://github.com/JF002/InfiniTime/blob/develop/nrf_common.ld#L136) and its current size is 8192 bytes. The heap is used for dynamic memory allocation(`malloc()`, `new`...).
+
+Heap monitoring is not easy, but it seems that we can use the following code to know the current usage of the heap:
+
+```
+auto m = mallinfo();
+NRF_LOG_INFO("heap : %d", m.uordblks);
+```
+
+#### Analysis
+According to my experimentation, InfiniTime uses ~6000bytes of heap most of the time. Except when the Navigation app is launched, where the heap usage increases to... more than 9500 bytes (meaning that the heap overflows and could potentially corrupt the stack!!!). This is a bug that should be fixed in #362.
+
+To know exactly what's consuming heap memory, you can `wrap` functions like `malloc()` into your own functions. In this wrapper, you can add logging code or put breakpoints:
+
+- Add ` -Wl,-wrap,malloc` to the cmake variable `LINK_FLAGS` of the target you want to debug (pinetime-app, most probably)
+- Add the following code in `main.cpp`
+
+```
+extern "C" {
+void *__real_malloc (size_t);
+void* __wrap_malloc(size_t size) {
+  return __real_malloc(size);
+}
+}
+```
+Now, your function `__wrap_malloc()` will be called instead of `malloc()`. You can call the actual malloc from the stdlib by calling `__real_malloc()`.
+
+Using this technique, I was able to trace all malloc calls at boot (boot -> digital watchface):
+
+- system task = 3464 bytes (SystemTask could potentially be declared as a global variable to avoid heap allocation here)
+- string music = 31 (maybe we should not use std::string when not needed, as it does heap allocation)
+- ble_att_svr_start = 1720
+- ble gatts start = 40 + 88
+- ble ll task = 24
+- display app = 104
+- digital clock = 96 + 152
+- hr task = 304

+## LVGL
+I did a deep analysis of the usage of the buffer dedicated for lvgl (managed by lv_mem).
+This buffer is used by lvgl to allocated memory for drivers (display/touch), screens, themes, and all widgets created by the apps.
+
+The usage of this buffer can be monitored using this code :
+
+```
+lv_mem_monitor_t mon;
+lv_mem_monitor(&mon);
+NRF_LOG_INFO("\t Free %d / %d -- max %d", mon.free_size, mon.total_size, mon.max_used);
+```
+
+The most interesting metric is `mon.max_used` which specifies the maximum number of bytes that were used from this buffer since the initialization of lvgl.
+According to my measurements, initializing the theme, display/touch driver and screens cost **4752** bytes!
+Then, initializing the digital clock face costs **1541 bytes**.
+For example a simple lv_label needs **~140 bytes** of memory.
+
+I tried to monitor this max value while going through all the apps of InfiniTime 1.1 : the max value I've seen is **5660 bytes**. It means that we could probably **reduce the size of the buffer from 14KB to 6 - 10 KB** (we have to take the fragmentation of the memory into account).

This is a function you'll have to define in your code. In this function, you can call `__real_malloc()` to call the actual `malloc()' function.

+## Simple method to generate a font
+
+If you want to generate a basic font containing only numbers and letters, you can use the above settings but instead of specifying a range, simply list the characters you need in the Symbols field and leave the range blank. This is the approach used for the PineTimeStyle watchface.
+This works well for fonts which will only be used to display numbers, but will fail if you try to add a colon or other punctuation.
