Re: Booting problem on Davinci EVM (Solved)
Hi, The problem looks like is with the serial port on my PC and not the board. I hooked up an oscilloscope and confirmed data coming out of the board but my PC serial port is not displaying anything.

Re: Booting problem on Davinci EVM
HI Carlos, I tried that I configured S3 for UART boot mode ( I tried both S3-1 and S3-2 in OFF mode and also in ON mode) but I am not able to see any messages on the UART console. I am not sure what can go wrong so suddenly but looks like UART has gone bad :( Regards, Meher On 12/29/06, Carlos Ojea <[EMAIL PROTECTED]> wrote: > Any ideas from on how to debug this and to confirm UART on board is > good/bad are appreciated.

Re: Booting problem on Davinci EVM
OK... I did some debugging using lauterbach and loading the U-boot to RAM. Looks like U-boot is getting stuck in one of the ns16550_reinit function which is getting called from serial_putc function. I am not sure why this is happening all of a sudden unless RS232 transeiver on the board has gone bad... Any ideas from on how to debug this and to confirm UART on board is good/bad are appreciated.

Re: Booting problem on Davinci EVM
If you load the elf image, it already have embedded the load address and the entry point, the lauterbach will set the pc to the proper location, just run... However I think in most places what's available is the uboot image on uboot format, so you need to download the source and compile by yourself.
