NXP B4860QDS J2 debug port

sread — Mon, 21 Dec 2020 08:08:21 GMT

Hello NXP Community,

I have a basic connectivity problem with my NXP B4860QDS J2 debug port.

I have closely followed the “Quick Start Guide for B4860QDS and B4420QDS” and I believe that all configurations and connections are made correctly and using only the hardware kit contents supplied.

However, after powering on the board, there is a problem with the J2 USB debug/eCWTAP connectivity as follows:

D1 (eCWTAP) LED is not lit at any time – neither orange nor green is observed. This suggests that eCWTAP is inactive.
Using both Linux Ubuntu 18.04 and Windows 10 operating systems and 2 different cables, no connectivity is detected on either PC USB port at any time.

This problem is fully repeatable.

Attached are photos showing:

Jumper Settings – set as default (J21 with CLOSE: 2-3)
DIP-Switch Settings – set as default (SW1, SW2, SW3, SW5)
LEDs (D1 is not lit)

Please could you suggest as to why the J2/D1 USB debug connectivity is not working as expected.

Please refer to CodeWarrior_PA_10.5.1/PA/ccs/drivers/usb/readme.cwtap.txt to install the udev rule and make it take effective on your Linux host PC.

NOR_BOOT switch setting.
---------

SW1 : 0x00 = 00000000 SW2 : 0xFC = 11111100 SW3 : 0x12 = 00010010
SW5 : 0x03 = 00000011

If there is no valid RCW on the target board, please use hard-coded RCW.

Please open CCS console and type the following command.

We have 2 boards. One is working with eCWTAP, and the second is not. Both have the same RCW. On the second board D1 and D2 LEDs do not lit and the LEDs on CWTAP Ethernet port do not lit also.

We can't use CSS console, as CWTAP USB\Ethetnet port does not work at all.
