I guess it makes sense that the addresses aren't quite the same; iirc ST has some licensing restrictions on their SVD/header files saying that you can't use them with other vendors' chips anyways.
Thanks for the extra information!
- magicalhippo 7y agoI'm guessing you're after the bare MCU, but for others, you can get a nice relatively cheap prototyping board with the chip from Sipeed, for example: https://www.seeedstudio.com/Sipeed-Longan-Nano-RISC-V-GD32VF103CBT6-Development-Board-p-4205.html https://www.seeedstudio.com/Sipeed-Longan-Nano-RISC-V-GD32VF... SeeedStudio has a few others as well: https://www.seeedstudio.com/tag/RISCV-Board.html https://www.seeedstudio.com/tag/RISCV-Board.html Just note that you need a relatively new J-Link (v10 iirc) to program RISC-V cores using J-Link, alternatively for the Sipeed Longan boards, pick up two of them and you can flash one with a provided debugging/uploading firmware.
- leggomylibro 7y agoYes, the Longan Nano is very nice but I'm also interested in the bare chips. Seeed also sells cheap JTAG dongles that work with their RISC-V boards, which is nice.
- cculpepper 7y agoI've been using a clone J-Link which works pretty good. I got it probably 5 years ago, so it's impressive that it works. I think I'm using a patched version of openocd with it though.
- cculpepper 7y agoWhoops, I meant TMall[0], its like aliexpress vs alibaba, or vice versa. Same buying process through a third party. Apologies for that. [0]https://list.tmall.com/search_product.htm?q=gd32vf https://list.tmall.com/search_product.htm?q=gd32vf
