MCU resets when reading memory

[hiredman]

Hello, I am pretty new to playing with the ch32v003 and ch32fun has been a great help.

If I read ram locations from the mcu like minichlink -r + ram 32, if I read it enough times the blue led that is normally off flashes on my wch-linke, and the mcu appears to reset. If I have counter that initializers to 0 in the memory being read I see it reset to 0.

This doesn't happen every time I read the memory location, but does every 3rd to 5th read, seemingly regardless of how long between the reads.

Am I just holding this thing wrong?

Thank you.

You don't really want to use a Link-E for isolated memory read operations, the process of re-calling minichlink with a Link-E leads to that because of the initialization process that's needed.

You can potentially try to use -G for GDB mode, it will create a gdbserver, then communicate over GDB protocol and/or use GDB.
