Hey,
We have been issues with using both the audio input and the UART1 on our LCDK and I suspect it is due to our interrupts in our asm files. We are using two separate sets of example code and have a interrupt .asm file from each set. However, our UART1 and McASP are both tied to the 4th interrupt in both files and I suspect that is causing an issue, but I do not understand ARM assembly and am not too sure. Is this causing the issue? If so, does anybody have any advice as to how we can fix it?
intvecs.asm
the McASP interrupt is tied to _c674x_mask_int4_isr
