Hi there,
I have problem while flashing the software to stm 32. I am using ST link for debugging.
Flashing was working fine, but after while, i am getting getting the error as “Error finishing flash operation”.
In openOCD i am getting the error as below.
Info : flash_write_start:0x8020400|0x80c7528|stm32f4x.flash
Error: timeout waiting for algorithm, a target reset is recommended
Info : flash_write_done:stm32f4x.flash
Error: error executing stm32x flash write algorithm
Error: flash write failed = 00000040
Error: error writing to flash at address 0x08000000 at offset 0x00020400
Info : Unable to match requested speed 2000 kHz, using 1800 kHz
Info : Unable to match requested speed 2000 kHz, using 1800 kHz
adapter speed: 1800 kHz
target halted due to debug-request, current mode: ThreadPlease help me to solve this problem.
Thank you
Hi,
Sorry, this looks like a bug in OpenOCD. As the OpenOCD’s FLASH programming logic is maintained by ST, we don’t have many insights into it, however based on our previous experience, trying to rearrange various sections of your program (e.g. making sure they are aligned and none of them is too small) should fix it.
You can also try building OpenOCD from sources as shown here. Alternatively, please consider trying Segger J-Link. It comes with its own GDB stub that is more reliable than OpenOCD, and usually just works out-of-the-box.
