IMX93QSB - JTAG Flashing/Debugging via USB-C (FTDI FT4232H) on Windows/Linux

[sergiomauro]

Hello Everyone,

I hope you're doing well. I’m currently seeking assistance on how to perform JTAG flashing and debugging on the IMX93QSB using the USB-C debug port. Specifically, I would like to know if this can be done using an FTDI FT4232H (Port A configured as JTAG) through the USB-C port. Is this functionality supported on both Windows 10/11 and Linux?

I’ve reviewed the Reference Manual but couldn’t find clear guidance on this feature. Could someone confirm whether this is feasible, and if so, provide the necessary steps to make it work?

Thank you in advance for your help!

Hello,

It is not be possible to flash the board using JTAG, please note that JTAG in the i.MX devices, excluding the RT family, is used for the debug purpose only.

Regarding OpenOCD, please take a look in the next presentation.

Best regards.

Hello,

thank you for the clarification.

Just to confirm, is debugging possible only with a SEGGER J-Link, or is it also feasible to use the USB-C port with FTDI FT4232H chip (configured with Port A as JTAG)? I’d like to understand if this setup would work for debugging, and if so, whether there are any specific configurations required.

Thanks in advance for your assistance.

Hello,

It is possible to debug using both methods, SEGGER J-Link and OpenOCD.

Best regards.
