Hi @jmn I just got the following reply from Reuben Townsend from GigaDevice:
Hi Kristof, the GD-LINK uses the CMSIS-DAP interface and for the GD32E230 MCU, you can use the stm32f0x.cfg configuration file. Attached is a script you could use. It didn't work on my computer. I'll ask him what to do for the Risc-V board. Anyway, the script he sent me is this one: interface cmsis-dap transport select swd source [find target/stm32f0x.cfg] What surprises me is that the GD-Link is based on cmsis-dap - which is an ARM Cortex standard. Not sure how they combine that with a Risc-V processor. For the datasheet on this Risc-V processor, see: [ https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=2ahUKEwja5ffQ-o3pAhX1JMUKHR90DC4QFjAAegQIDRAB&url=https%3A%2F%2Fdl.sipeed.com%2FLONGAN%2FNano%2FDOC%2FGD32VF103_Datasheet_Rev1.0.pdf&usg=AOvVaw3vDRLt14BC1Msb24ENRqRL | https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=2ahUKEwja5ffQ-o3pAhX1JMUKHR90DC4QFjAAegQIDRAB&url=https%3A%2F%2Fdl.sipeed.com%2FLONGAN%2FNano%2FDOC%2FGD32VF103_Datasheet_Rev1.0.pdf&usg=AOvVaw3vDRLt14BC1Msb24ENRqRL ] Kind regards, Kristof Van: "j. m. norris" <u17...@att.net> Aan: "openocd-devel" <openocd-devel@lists.sourceforge.net> Verzonden: Woensdag 29 april 2020 16:57:25 Onderwerp: Re: [OpenOCD-devel] Support for GigaDevice microcontrollers Kristof, Can you send a link for the RiscV board documentation? I might be able to help as I've work with other RiscV boards.
