I bought the ls1021astn-pa board,but the img in the sd card didnot work,so i want to know where can i find the ls1021astn. img file.
Is the board in question LS1021ATSN-PA?
If "yes" then please consider that the LS1021A-TSN board is built by VVDN/Argonboards in partnership with NXP.
As such, the data is provided by them - see Software & Tools, Pre-built Images:
Thanks for your answer,i will try to get it.
