Bootloader HardFault Error Peripheral

[Hi world!]

Hi guys,

I'm using a bootloader. I am using 2 UART channels in the bootloader program. At the same time, I use these uart channels in the program I will install. But they don't work. The program enters the HardFault Error interrupt. When sending data to the uart channel when debugging, the program is corrupted and enters the HardFault Error interrupt.

What can I do?

Thanks..

>>This general problem. But no enough information.

So have you looked at the registers and faulting instructions? Hard to debug remotely. Harder with no detail from the remote end, and selective cut-n-paste of code that may or may not be relevant to the failure.

In Keil the stack size is defined in startup_stm32f0xx.s

You need to make sure the app doesn't use the base of RAM you're using for the Vector Table, and that the RAM is remapped properly.

Make sure it is linking the correct library, 32-bit ARM libraries will not execute on a CM0, code built for the CM3 or CM4 will likely also fail.

[Hi world!]

I can't understand this file. Can you help me?

Thanks.

>>Can you help me?

Does it pay well? I have a fence that needs stripping and repainting, can you help with that?

Stack_Size EQU 0x400 ; << make this more bigger

[Hi world!]

I am student man. If i work job i pay you. But now Can you pay me :)

[Hi world!]

I changed 0x800 but result not different. :(

[Hi world!]

Any ideas? ​

[AvaTar]

Did you mention the toolchain ? I can't remember.

The file you posted might get rewritten, better change the stack size in the project properties.

Try single-stepping in the debugger.

Get someone tutoring you on site.

Doing this over such a forum will not work out, there is much for you to learn.
