Other Parts Discussed in Thread: TM4C1294NCPDT
I recently obtained MSP432P401R Launchpad and latest CCS v12 logged an error communicating with its onboard XDS110-ET. So I reflashed the firmware using the firmware_3.0.0.25.bin bundled with the CCS, following the instruction in XDS110SupportReadMe.pdf (included in CCS as well). Now it does not even recognize as an USB device.
I'm trying to recover using a separate JTAG adapter (J-Link), but so far, no firmware seems to work at all. Can anyone advise me on 1) which firmware image, and 2) which flash memory address I need to reflash to get this working again?

I tried both firmware_3.0.0.25.bin and boot_loader.bin - I flashed them to 0x00000000 (flash start address of TM4C1294NCPDT chip, used by XDS110-ET) but both ended up being device not being recognized (does not even show up on USB bus). I am certain flashing itself was successful, as flash programmer verified it OK and I was also able to obtain the expected image with separate readback.
I also got TM4C1294 (re-)enter DFU mode by erasing the flash. While it does enter DFU mode, xdsdfu.exe fails to reflash the device with the error DFU_ERR_UNKNOWN (-4).

I'm puzzled. Could it be that this rev1 version of MSP-EXP430P401R Launchpad is somewhat different and not compatible with provided XDS110 firmware in CCS?
