  • Forum Post: Bug in the generic EDMA McBSP driver?

    Robert9862
    I'm working on a IOM mini-driver based on the generic EDMA McBSP Device Driver for TMS320C6x1x DSPs (SPRA846A). In my opinion, there is a bug in c6x1x_edma_mcbsp.c which turns up when using two instances of the driver on a c6713 dsp: On line 675 both instances get the same EDMA channels and therefore...

    I am using OMAP-L138 EVM with CCS4 trying to evaluate DSP/BIOS 6 on the DSP core and Linux on the ARM core. I am using the builtin XDS100 for debugging. I don't have any issues w/ the Linux side, but the BIOS timing seems way off. I wrote a basic "blinky" app in a BIOS task to blink the...

    Champs, I have a question about kernel timer (or tick generation) for DSP/BIOS 6 (exactly 6.21.00.13). Yes, using together with CCS v4. My background is multicore C64x+ DSP (or Faraday).. So far, we can specify which hardware timer is used, or which HWI vector is assigned, and which core should...

There certainly is not enough RAM on this chip...
