RE: USB over Console not working on custom board

Hi,

Do you use static partitioning or partition manager? If you use static partitioning, you can look at this pm_static.yml and app.overlay example. If you use partition manager, you can look at external flash memory partitions in the documentation. You can also have a look at this blogpost which shows external flash configuration and overlay.

Do you get any errors when using USB console sample with LittleFS and external flash?

Best regards,
Dejan

HI dejans thanks for the example , we workred it out it works fine on bare device without any external spi flash configured .

our custom board uses external flash for littleFS . so when we use this usb console with the flash and littleFS configuration , we have failed to use usb again, means we dont see any COM port of USB when we flash the code.

Any idea what might be causing this ?

my device tree looks like this

and main file and overlay file is same as example you provided in previous comment .

please let me know what i am missing .

Hi,

There is an unofficial hello_world_usb sample which demonstrates how to use CDC ACM USB for logging. Can you try it out?

Best regards,
Dejan

Hi sir dejans waiting for your reply .

I have a custom board that has a USB port .

i use J-Link which has vdd, swdio,swdclk ,reset, and ground wires that connect to custom board .

also another nordic product we work on has NO USB port , only a jlink connecter to flash the firmware .

please tell me how i can see logs/traces on both of these devices/custom boards

Hello Dejan

I am having a very tough time regarding this issue .

I am using sdk 2.6.0 but now I have downgraded to 2.3.0

same with tool chain .

sample I use is , zephyr/samples/subsys/usb/console

please help ,

after your valuable feedback please answer X1

X1- If we upgrade on sdk will the way of using samples also changes ?

Hi,

Which NCS version do you use?

Could you provide a link to the sample which you use?

Best regards,
Dejan
