McBSP DMA Event [DM355]

Hi, I have enabled McBSP0 in the board-dm355-evm.c file. I have configure McBSP0 for audio but it is not working( Currently I am using McBSP0 for only recording purpose...). I found that McBSP1 EDMA event is enable in mcbsp.c file by following code: if (cpu_is_davinci_dm355()) { __REG(EDM

Hi Steve, When I check /proc/pinmux it shows that Pinmux is configured for McBSP 29:34 but when I see the schematics it shows that McBSP pins are on 25:30. Can you please tell me how do i enable event mux for McBSP0 pin 25:30? On Mon, Apr 27, 2009 at 5:18 PM, Steve Chen wrote: > On Mon, 2009-

Hi Steve, After looking into the PINMUX I found that the pinmux setting is being done when I call board_setup_psc(DAVINCI_GPSC_ARMDOMAIN, DAVINCI_LPSC_McBSP0, 1); This does the PINMUX settings for McBSP0. I found two patchs on the mailing list for McBSP0 setup... tx_swap.patch rx_swap.patch htt

Re: McBSP DMA Event [DM355]

Hi Steve, I have tried setting PINMUX3 to 0x3F as well as 0x00. In both the cases I get the same error "frame sync not detected" Below is the code snippet where I get this error: pcrtemp = PCR; /*Enable the transmitters pins as GPIO*/ PCR = PCR | RIOENABLE; /*Wait for the first fra

Re: McBSP DMA Event [DM355]

Hi Steve, Thanks for the help. I got the McBSP0 working for my audio chip. Other than the changes you suggested I had to disable the internal clock of McBSP0. Thanks a lot for your help. Best Regards, Azam. ___ Davinci-linux-open-source mailing list D
