Strange... there is a good hint that your hardware is probably working, at least up to a point: the entire bit before the gdb connection is expected and good. Not sure what fails after that, though... you could possibly try lowering your adapter_khz, sometimes that makes a difference.

So this is the complete script as I understand it. This obviously could have a bug in it but is here to maybe help someone work through the issue. May have to raise a bug (Suspect same audience)

A new question and an update.
I see in the header for ft232r.c it has the following.

Question

Code: Select all

#define FT232R_BIT_COUNT 8
static char *ft232r_bit_name_array[FT232R_BIT_COUNT] = {
        "TXD", /* 0: pin 1  TCK output */
        "RXD", /* 1: pin 5  TDI output */
        "RTS", /* 2: pin 3  TDO input */
        "CTS", /* 3: pin 11 TMS output */
        "DTR", /* 4: pin 2  /TRST output */
        "DSR", /* 5: pin 9  unused */
        "DCD", /* 6: pin 10 /SYSRST output */
        "RI"   /* 7: pin 6  unused */
};

static int tck_gpio; /* initialized to 0 by default */
static int tdi_gpio = 1;
static int tdo_gpio = 2;
static int tms_gpio = 3;
static int ntrst_gpio = 4;
static int nsysrst_gpio = 6;
Usually I have my board set up like shown in
https://docs.espressif.com/projects/esp ... -jtag.html
MTDO / GPIO15 - TDO
MTDI / GPIO12 - TDI
MTCK / GPIO13 - TCK
MTMS / GPIO14 - TMS
GND - GND

And doing this results in the output.

Code: Select all

Info : 518 28 core.c:1027 jtag_examine_chain_display(): JTAG tap: esp32.cpu0 tap/device found: 0x120034e5 (mfg: 0x272 (Tensilica), part: 0x2003, ver: 0x1)
Info : 519 28 core.c:1027 jtag_examine_chain_display(): JTAG tap: esp32.cpu1 tap/device found: 0x120034e5 (mfg: 0x272 (Tensilica), part: 0x2003, ver: 0x1)
But looking at the header file it says GPIO 0-6. When I use this I do not see the JTAG messages but instead errors which I am taking to mean it does not work configured this way.

So my question is more around the ntrst_gpio, nsysrst_gpio which are not mentioned in the espressif link only tdo, tms, tdi, and tck.

Progress
I have raised a bug with the ocd espressif people https://github.com/espressif/openocd-esp32/issues/157
They have been responsive but no been able to help with a positive outcome. They have said that the log I provided looks like it is working. Last part shown. However it hangs on the GDB side with no prompt ie. no (gdb)
