imx6ul evk version B & C

healy — Thu, 28 Jun 2018 05:25:43 GMT

I have 6UL EVK version B, but I see the AN5229, in the AN, user case for kernel debug is with version C,

May I know the difference? can I use the versionB EVK to debug linux knernel source code with Dstream in DS-5?

thanks a lot!

Hi Healy

differencies between B and C are described on p.1 schematic

Table"Revision History"

>can I use the versionB EVK to debug linux knernel source code with Dstream in DS-5?

yes, differencies between B and C are changing some resistors and adding components for

passing fcc tests and not affect jtag debug operations.

Hi Igorpadykov

I had followed the AN and now I can debug kernel( can run/stop & step/step into, view variable successfully) in DS-5,

issue I encountered is - I can't input any command in terminal after perform debug running command!

I plan to use "insmod" command to invoke my device dirver & debug it. but I found I can't input any command in terminal after "connect the EVK & debug run"

had you any idea about that?

Thanks you so much!
