JTAG debug with SD card

Postby marius.rangu » Wed Nov 22, 2017 4:24 pm

Is there any way to use a JTAG debugger on WROOM32 while running a code that uses an SD card connected on a 4-bit SDIO?

Thanks!

No, the pins of JTAG and SDMMC interfaces overlap, so these two can not be used at the same time.
