Easiest way to get rid of __clz_tab in winavr compiled code?

I've ported a program from the arduino environment to a makefile build using winavr, which, in turn, is based on avr-gcc (just like arduino). However, my program started crashing, and after some investigation I found I was running out of data memory…

Make linker use bank 0 in relocatable mode

I'm tryin to build assembly project with MPASM/MPLINK for PIC16F628A. Microchip advice that it's better to stay on bank 0 and switch whenever you want different bank, and then get back to bank 0 (to minimise bank switching). That's why I want to put…

How does avr-gcc linker know to put the `.data`section at `0x800100` rather than `0x800060`?

Looking at the linker script for my part (ATMEGA168PD), the data region has an origin defined as starting at 0x800060... MEMORY { text (rx) : ORIGIN = 0, LENGTH = __TEXT_REGION_LENGTH__ data (rw!x) : ORIGIN = 0x800060, LENGTH =…

Bus Fault Handler when writing to a memory provided by a linker script

I have to work with code written by someone else for the Cortex M3-based board. I know that this code is supposed to work and it used to pass its integration test: the code is flashed to the board using openocd and then a Python script asserts that…

Porting a linker script from STM32F1 to STM32F2

I am trying to port PyMite from STM32F1 to STM32F2. One of the files that I am assuming must be changed is called stm32f10x.ld. I have looked around for an equivalent of this (called stm32f2xx.ld?) but haven't found anything. I'm now thinking that I…

ESP8266 and GCC

I think this is more related to GCC rather than ESP8266. I have been trying to put in a constant variable in read only memory section of ESP. The idea is to change the value directly in the binary image before flashing it on a new chip. In the code…
