Is there a method such as dvflasher for programming the bootloader (UBL and u-boot) to Nand flash on the EVM355 via the uart .

Here is an example for a serial port: int uartWaitForData(int milliseconds) { int maxfd = uartfd + 1; // create the maximum FD to look for fd_set readfs; // file descriptor set struct timeval timeout; int result; //----- set the timeout value timeout.tv_sec = milliseconds / 1000; timeout.tv_usec = milliseconds * 1000; FD_ZERO(&readfs); // clear the file selector set FD_SET(uartfd, &readfs); // add file descriptor to the file selector set result = select(maxfd, &readfs, NULL, NULL, &timeout); // see if any chars if (result <= 0) return (-1); // if (FD_ISSET(fd, &readfs)) // see if ready to be read // return (1); return (1); } I was merely looking to see if it timed out... and it MIGHT help you determine if port closed (I don't know). YMMV as they say. Good luck!

We have replaced the decoder, removed the MSP430, redesigned the switcher etc... I also - by accident - moved the audio codec to McBSP0, when the original device was using McBSP1. Because of this, quite a few things in the MVL (yes we are using 2.6.10) distribution had to change. It seems that there was a bit of hacking to make the audio work with the 355, and none of it considered that you might want to use a codec on the other McBSP. So, here is my problem - the DMA channel that is "assigned" for the audio_open() (davinci-audio.c) function is wrong. And I can't figure out where it is coming from ! Here are some snippets from davinci-audio.c this structure is exported with platform_device_register: /* Device Information */ static struct platform_device davinci_audio_device = { .name = DAVINCI_AUDIO_NAME, .dev = { .driver_data = &audio_state, .release = audio_free, }, .id = 0, }; ... audio_state_t *state = (&audio_state); ... audio_stream_t *is = state->input_stream; ... DPRINTK("DMA REQUEST FOR record\n"); DPRINTK("Channel requested %d, DMA dev %d\n", is->id, is->dma_dev); DMA_REQUEST(err, is, audio_dma_callback); So what I see is that 'is->dma_dev' is being passed to me as a 9. This corresponds to the EDMA channel for ASP1 - not zero like I want. I confirmed that this was indeed the problem by forcing the channel to 3 (ASP0 for record) and I suddenly have tons of dma ! But I need to fix the underlying problem ... Can anyone tell me who or what determines the DMA channel for the audio? Thanks!
