I'm sure that the st-link on stm32f3discovery, connection stm32f103 <> st-link and supply is ok. Is it possible to software reset flash page or unprotection some page?

Is it possible to software reset flash page or unprotection some page?

Yes, via the ST-LINK utilities, or via the serial port an the Flash Loader Demonstrator (or custom app talking too the System Loader), or code you write yourself that runs on the STM32. The Segger J-Link may also have additional tools/features. It this point you might want to try some additional boards, or remove the part and replace it with another one.

I write a simple program to blink led, export to .bin and send by st-link utility and it's working but when I try send program with interupts handling I get error.I think that pages responsible for interupts are write-protection(?). Could you write a program which will unprotect these page?

Hello Karol,

The STM32F10x standard peripheral library firmware package contains an example to enable/disable Flash pages write-protection.

Please visit this link :

http://www.st.com/web/en/catalog/tools/PF257890

and go under ''STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\FLASH\Write_Protection''.

You can also use ST-LinkUtility to disable protection by unselecting protected pages as follows :

Target -> Option Bytes -> Flash Sectors Protection. Best Regards, Nouha

Hi, I try it but again I have error with some flash pages. It is possible that they are damaged?

If this were my problem I might, but I'm not sure I want to commit resources to it, it would be easier for me if you try other chips, or builds of your board, to confirm if it's just this one chip that's broken. The reported failure is not in line with the write-protect groupings the option bytes describe.

Hi karol,

  I didn't read all conversation, but i can tell you that i had some problems with flashloader tool in the past. I don't know why, but every time i installed flash loader program i was able to flash program to processor only once. After that, i always got same errors as you posted in the picture somewhere above. I don't know how this is possible, but then i solved my problem just by using another pc. Both pc had same windows, version of the tool was the same, and with one computer i never had a problem, and with another i was able to flash processor only once. I don't know how that is possible, but i suggest you to try another computer to do the same tasks and see how it goes.Cheers, Arganas

Hi karoll,

Do you still have the poblem? May be it is related to Hardware you have used. - Try to load another example in the same board. - Try to load the same code in another board. let me know about results. Best Regards, Nouha
