Tiao Jtag adapter (tumpa) pb

[adesandr]

Hi,

I bought a tumpa V2 Jtag adapter.
I’ve tried to use it under windows 7 and Linux Ubuntu 18.04, but the Jtag interface is not detected in both case.

Under windows, I’ve downloaded the ftdi drivers and installed it with Zadig. Interface 0 & 1 seems to work properly when I look the device manager, but when I’m running openocd, I have an lib_usb_open error.

Under Linux, I’ve downloaded the ftdi drivers (v 1.4.8) and installed it as recommandés by ftdi. Using lsbus et lsmod i can’t seen that the board it detected, but using openocd, same problem, the Jtag interface can’t be open.

So, I’ve read that espressif used internally some tumpa adapter, please can you share the step-by-step process to configure a tumpa at least under Linux to use with openocd ?

I left the tumpa jumpers on the board with the default positions, maybe some jumpers needs to be moved (if you have some photo, it will be kind to share) ?

Thank you in advance for your help.

Regards.

Not sure about Windows, but Linux does not need any drivers installed (and possibly installing the FTDI drivers broke your setup). Can you post the specific OpenOCD output?

Hello,

Thanks for your reply,

when I plug my tumpa, lsysb gives me :

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

So it seems that my tumpa is recognize by the system.

When I launch, udevadm -k -p, I obtain the following when I plug my tumpa

Looks like OpenOCD detected and configured an adapter; unless you have other jtag adapters connected to your machine I'm going to assume it's the Tumpa. However, it can't see the ESP32. Are you sure it's connected properly, and that any application you may have running on the ESP doesn't reconfigure the JTAG gpios (12-15) to something else?

Hello,

I was probably a little bit tired.

In fact I was a problem of wiring between my tumpa and my ESP32 board.

All is working properly now and effectively the installation of the D2xx ftdi driver is not mandatory under linux (i'm working on ubuntu 18.04 LTS). ftdi_sio & usbserial drivers are working fine.

Thank you for your help.
