Debug port not working on LS1021A-IOT

[bordeaujean-pas]

Dear all,

I have purchase an LS1021A-IOT reference design from mouser and make basic tests without issue... And now, my serial debug port doesn't seems working any more!!!

Have you some idea?

Best regards.

Before my issue, the Uboot trace was the following :

Please refer to the following Community question concerning the MBED misbehaviour when connected to Windows 10:

https://community.nxp.com/message/1054604?commentID=1054604#comment-1054604 

The LS1021A-IOT also has K22 microcontroller running the CMSIS -DAP firmware.

[bordeaujean-pas]

I have follow the instruction and copying the k22fx512_if_mbed.bin.zip (or the k22fx512_if_mbed.bin) on the mapped volume labelled ‘MBED’,

after the volume’s remap, a file fail.txt appear containing “SWD ERROR”!!!

No change.

Any other idea?

Thank for your help.

Have you performed firmware upgrade/programming operation(s) before the failure?

[bordeaujean-pas]

First, I have made another sdcard to keep the reference one…

I have perform nothing around upgrade/programming operation(s) before the failure, except toggling sdcard an reboot…

Could you toggle the SD card again (insert the original one)?

[bordeaujean-pas]

This is what I have already perform several times before posting this trouble…

Ensure that all configuration switches are in default positions.

What is the LED D5 behaviour? - refer to the QorIQ LS1021A-IOT Gateway Reference Design Getting Started Guide, Table 2. LED operations.

Do you have CodeWarrior IDE and CodeWarrior TAP to debug the board?

[bordeaujean-pas]

- Configuration switch are : SW2[1 :8] OFF OFF OFF OFF ON ON ON OFF compare to OFF OFF OFF OFF OFF ON ON OFF (reference manual)

=> S2.5 “0 : SerDes Lane 2 – SATA”

- LED D5 (K22) behaviour :

- off when booting without USB cable

- on when booting with USB cable

- blinking when sending character from the computer

I don’t have any CodeWarrior tools…

Try to uninstall and re-install USB MBED driver on the host PC.

[bordeaujean-pas]

I don’t have installed any USB MBED driver… My machine is an Ubuntu (Linux) and I just use minicom…
