CCS/IWR1642BOOST: IWR1642 usb serial ports problems
Part Number: IWR1642BOOST
Tool/software: Code Composer Studio
After flashing the boot-loader binary on the IWR1642BOOST board through the xdsdfu firmware update utility, the usb ports /dev/ttyACM0 and /dev/ttyACM1 were no more available under /dev/ folder and also in SmartRF Programmer 2, SmartRF Studio or CCS.
Could it be anything wrong with the TM4C1294NCPDT MCU ?
Do I have to buy another board ?
What are you trying to do and why are you using SmartRF Programmer 2, SmartRF Studio.?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Charles Oladimeji:
I was trying to do a kind of hard reset of the board. Probably, It wasn't a good move .
Anyway using the XDS drivers I wasn’t able to upload the boot loader binary.
Do I have to change the board ?
It seems like the TM4C1294NCPDT MCU isn't recoverable.

Hi Charles,I have installed the XDS drivers, but the COM Ports for the IWR1642BOOST EVM weren't available as well.I guess that the TM4C1294NCPDT MCU responsible for the USB connection is damaged, doesn't it ?Regards,Angelo
Can you provide some more details on the problem? Was this a working board that stopped showing the COM ports?
Hi Charles,Yes, It was. After flashing the bootloader binary It hasn't worked anymore. The COM ports weren't available anymore.I was using the xdsdfu tool provided by the XDS Emulation Software (EMUPack) https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_xds_software_package_download.html.Regards,Angelo
Why were you programming TM4C1294NCPDT MCU to begin with?
The EVM comes with the firmware for the emulator preinstalled. You only have to install the driver on your PC.
You followed the instructions in the link below and that didnt fix it?
Hi Charles,Sorry, I expressed myself badly, I didn't program directly the TM4C1294NCPDT MCU,and you are right, I followed the instructions in the link and that didn't fix it, indeed the COM Ports weren't available anymore.Regards,Angelo
You may need to replace the board.
Charles OladimejiCan you share a picture of your setup?
Charles OladimejiWhat is the spec of the power supply used?
Charles Oladimejiwhat caused the failure?
