5777c eQADC A and B

Hello,

I'm using 5777C with S32DS PA

I measure 16 channels from eQADC B(sw triggered cont scan) and 2 channels from eQADC A(hw triggered cont scan).

eQADC A, and eQADC B is working well if I use the eQADC separately, but one of them is not working when I use both eQADC A and B.

Last initialized eQADC is working well, but first one is not.

Anyone has an idea for solving this problem??

Thank you for your help.

I found there is a bug in the eqadc_driver.c in SDK.  

Also, another article regarding this issue has already been posted.

Please read the post below:
