Forum Post: RE: EDMA3 code crashes my code

Hi Pubesh,

Finally I got through!

I was not setting intermediate chaining code to the same channel from where the tranfer is triggered in the PaRAM set. I did it and all started working fine. But no where in the EDMA3 document it is reinstated that in A-Sync mode if CCNT and BCNT is greater than 1 on in AB
Sync mode if CCNT is greater than one ITCHEN must be set to get the work done . Or else, am I getting it done the way it is not intended to be? 

If this is the right way then please modify the document with this information as an important one not to be missed by those who dive deep into the EDMA3 peripheral. If this is not the correct way and if I am missing some thing then I would upload the PaRAMs which I set. 

But with all these I am left over with some pending issues.

They are,

Why the pre-compiled version is different from the source code?
please see the earlier posts about how I reached till here.
 
What happened at the semaphore pend and why it misbehaved inside drv_open API?
 
If a mere recompilation would work for the source code, then what is the procedure to get it recompiled again.

 regards,

Sijomon Irinjalakuda
