After receiving the hex values i need to trnsmit these value through the CAN controller. the actual task was to to receive hex data from terminal like 0圆6, 0x55, 0x44, 0x23, 0x11, 0xaa, 0xbb, 0xcc via UART. hex st-flash -format ihex write firmware. So, finally i was able to find out the solutions. bin st-flash write firmware.bin 0x08000000 or, flash. ![]() Optional erase to clear existing filesystem. Do "objcopy -help" to see a list of supported ELF formats and choose the one that matches your original out.elf file. Nucleo and Discovery boards typically include a built-in ST-Link programmer. Note that the foo2.elf copy is much smaller than foo.elf because foo.elf was compiled with -g and has lots of debug data that was lost in the conversion to hex.Īgain, this is for ARM32. $ arm-none-eabi-objcopy -I ihex -O elf32-littlearm foo.hex foo2.elfįoo2.elf: ELF 32-bit LSB relocatable, no machine, version 1, stripped hex for a hex file Type: avr32-objcopy I ihex O binary myfile.hex myfile.bin. ![]() In your documentation always refer to the address as the 7-bit address. In your I2C code, make sure every I2C function takes the 7-bit address as an argument and not the 8-bit address. $ arm-none-eabi-objcopy -O ihex foo.elf foo.hexįoo.hex: ASCII text, with CRLF line terminators In my experience, the most common way of expressing an I2C address is to use the 7-bit form in hexadecimal. This is on Linux for 32-bit ARM, but should work on all architectures and platforms:įoo.elf: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, not stripped
