Re: [OpenOCD-user] Gotek with Artery AT32 programming

[Dethernal <det...@gm...>]

Thanks, I start to dig in code, but I have a question:

struct stm32x_flash_bank has to be filled, but what are 
user_data_offset, option_offset, ppage_size etc? For now I try to hack 
it as fast as possible, just append stm32f1x file.

I found source for values in this reference manual: 
https://www.arterytek.com/download/RM_AT32F415_EN_V1.03.pdf
Looks like address 0xE0042000 at MCUDEVICEID is correct way to identify 
this product.
Also, Flash memory size register is 0x1FFFF7E0, but in 
stm32x_get_flash_size it linked to CORTEX_M3_PARTNO branch, but Artery 
AT32F415 is Cortex M4. I probably need to add code to ensure that I will 
get right address... Just to remember.
