Re: MicroSD hangup

I'm also trying to find simple reproduction code or procedure That would really help! I tried some obvious ways to reproduce this (such as, place an abort() call into sdmmc driver, to simulate a crash while reading from the card; reset the ESP32 externally while read is in progress) but so far the ...

Re: Problem: Setting up JTAG debugger for ESP32

It's strange that gdb still says No symbol table is loaded. Use the "file" command. Make hw breakpoint pending on future shared even though the command file is specified after the elf file. Could you please try renaming .gdbinit into gdbinit (without leading dot) and try again? Maybe gdb is loading ...
