ESP32-LyraT-Mini V1.2 - JTAG setup

Postby J.Lunz » Thu Mar 26, 2020 3:53 pm

Hi:

I am trying to setup JTAG on a ESP32-LyraT-Mini V1.2 with an FTDI-2232H-module.

I get the following output:

Code: Select all

openocd -f board/esp32-wrover-kit-1.8v.cfg

Adding a SD-card changes the tap-section output like this:

Code: Select all

Info : JTAG tap: esp32.cpu0 tap/device found: 0x4c000099 (mfg: 0x04c (SCI), part: 0xc000, ver: 0x4)
Warn : JTAG tap: esp32.cpu0       UNEXPECTED: 0x4c000099 (mfg: 0x04c (SCI), part: 0xc000, ver: 0x4)
Error: JTAG tap: esp32.cpu0  expected 1 of 1: 0x120034e5 (mfg: 0x272 (Tensilica), part: 0x2003, ver: 0x1)
So I suspect the SD-Interface is interfering, do I just need to remove R128 or is there another way setting it up?
