Other Parts Discussed in Thread: EK-TM4C123GXL

Hello,

I have EK-TM4C123GXL. It works with CCS in Windows but in Linux I got error when try to run some example.

Error message includes suggestion to update firmware using ti/ccsv6/ccs_base/common/uscif/xds110

I did it and it was my mistake. Now board does not recognized by USB.

As i understand I flush firmware for XDS110 but board has Stellaris In-Circuit Debug.

I can connect to the board using another LaunchPad with XDS110 and flash correct firmware, but I don't have it.

Where can I get firmware for EK-TM4C123GXL Stellaris In-Circuit Debug?

Hello Michael

If the on-board ICDI has been corrupted, then the device is most likely locked itself out. You may have to order a new board.

What do you mean locked itself?
I can read/write flash in TM4C (that use for ICDI) by external JTAG

Hello Michael,

You will have to run the unlock sequence using external JTAG (based on the external JTAG being used) as given in the following application note

www.ti.com/.../spma075.pdf

Once that is done, you can restore the original ICDI by using Firmware Upgrade in LMFLashProgammer.
