Hello, We have a new board based on imx31. I am trying to bring up uboot on the board.I upload uboot through jtag using RVI debugger and run from RAM. But uboot hangs after printing a few greeting messages.Sometimes it could come till the uboot prompt. When I debug it on RVI, the error message it gives is memory access vioaltion. I don't have a source level degugging available right now. So I compare the disassembly from RVI to the u-boot.map file. WHat I could find is that it fails while printing to console(vsprintf.o).I could not exacly map to the correct line of code. The uboot hangs when trying to branch to a location which is not defined (BLNE 0x89533926). On my board the memory is mapped from 0x80000000 - 87FFFFFF. The uboot is based on the imx31 litekit patch that was posted and it was working well on a imx31 freescale ADS.THe memory map for our custom board is same as that of imx freescale ADS board. But I am not sure why it branches to some undefined location. Any help is appreciated.
THanks, Shiju
