Hello,
I recently got a Maixduino and even dough PlatformIO has on the docs page that it is possible to Debug the Maixduino with a JTAG adapter (I also bought a Sipeed USB-JTAG/TTL RISC-V Debugger for that reason) there I didn’t find how to hook it up. If I look at the JTAG pins on the schematic of the Maixduino they don’t seem to be accessible trough the IO headers. Do I miss something or is it impossible to hook JTAG up to a Maixduino without soldering wires to the JTAG Pins?
Hi there~
If the JTAG pins aren’t accessible through headers, it is possible that jumpers may solve the problem. If this problem still exists, you can also ask Sipeed support team at sipeed@support.com for advanced information.
Thanks cheers,
JL from Seeed.
Hi,
We had the same impression from looking at the Maixduino schematics, so we’ve published a tutorial on getting the JTAG wiring to work. You can find it here: https://visualgdb.com/tutorials/arduino/maixduino/
