Hi, I have some of this MCUs, after some research seems that openocd doesn't have a flash driver for this chips, based on ST32 I can init the MCU, reset, halt, resume, set breakpoints, etc. All of this seems to work.
For the flash driver, I wrote one based on the public datasheet available on : http://www.sonix.com.tw/list-en-999 I have some doubt about how to contribute the code: 1. Where is the contribution procedure documented, I never contributed to openocd, and after reading the website, it's not clear for me where to send the code for review. 2. Actually I only have SN32F700 MCU that is a Cortex-M0 based one, reading other SONiX datasheets seems that the flash erase/program procedure is a bit different in each family but very similar, now I wrote all prefixed with sn32f700_ but could be more flexible to prefix as sonix_ to add support to other MCUs in the future. In this context I haven't any method to detect the chip model, I'm asking SONiX about this. Regards, Marcos
