Re: JTAG IDCODE ON ESP32-U4WDH

I saw your note about openocd version after my last update. I have now updated openocd to v0.10.0-esp32-20200420 which seems to be much more successful, at least at 500 KHz. There were a couple of intermediate versions of openocd in my "dist" folder but it is not obvious on how to update the version...

Re: JTAG IDCODE ON ESP32-U4WDH

I Went up a couple of wire sizes to ensure solid connections, I am running at 500 KHz for JTAG Speed. I am now back to using the solo-1 configuration file for openocd. Overriding SPI voltage to 3.3. One of the other postings indicated that -c "gdb_breakpoint_override hard" might help. I am still get...

Re: JTAG IDCODE ON ESP32-U4WDH

I have dropped the JTAG speed to 500k, If you have information that lower speeds are appropriate, please let me know what can be expected to work.

JTAG IDCODE ON ESP32-U4WDH

My other two devices respond and I get Info : 394 874 core.c:959 jtag_examine_chain_display(): JTAG tap: esp32.cp...

Re: Deep Sleep Current too high (1-4 mA), even without LDO

I have not taken a close enough look at this device to be sure but I expect you are feeding the internal GPIO resisters among other things. I would try making all the GPIOs you are not using inputs without any pull-up/down features enabled. I know that I was able to reduce my average current on a AR...
