    David Anderson11625
    Hi there, thank you all for the detailed and informative replies. By the end of Friday I had figured out that the parameter "bios.UDEV.instance("mcasp0").deviceId" referred to the number of the physical McASP to be used in that driver. I put a big old comment in the code to that...

I need to make a simple USB PC / board communication (HID is ok for me). Does anyone be successfull writing...

    Dear Daniel Thanks for you suggestion, I have looked up in TI's website, and also have looked at the datsheet about TMS320C6745/6747 , However , no QFP [PYP suffix] were be founded, just only BGA [ ZKB suffix] package for TMS320C6747, and 6748 too. Are you sure that the 6747 include QFP(Quad...

    Yes, 256M of SDRAM space is enough, but more than two 16-bit EMIF interface are asked for FPGA and FLASH Another question is confused me : as you say , the 6745/6743 include 16-bit interface ,Are the 32-bit instruction can run in a 16-bit width SDRAM ? the 32-bit variable can be accessed or storaged...

    I set up my board with external circuitry (controlled by an MSP430 that we needed anyway), so that it can boot from NOR flash, UART2, or EMULATION mode. This is done by configuring the BOOTx pins with configurable pullup or pulldown resistors. The bootloader documentation tells which pins do what. To...
