Binary code does not run.

[alfredolopez]

Hi, I have my own LPC824 hardware working fine. I have developed with MCUXpresso 11.0.0 and I have experienced no problems, but when I generate binary to download it with an external bootloader it does not run. I attached debugger to analize the problem and I can see that   USART_TransferCreateHandle() function jumps to HardFault_Handler.

Should the binary be the same as .axf executable? Do I must change any settings at compile-linking time?

Hello Alfredo Lopez .

What about your external bootloader, does a UART bootloader?

And what about the address about bootloader? What about the start address of your image?

Regards,

This issue is solved. Thank you Alice for your appointment. The external bootloader changed several bytes that made the code unstable. Once directed the external bootloader to not change anything on binary file, the code runs fine.

OK, thanks your sharing.
