Intellectual 345 points

Hi,all

   I use the 8127evm to run the IPNC  demos. and i use uboot to initial the evmboard . it works well .but when i just change the core board to 8148,without changing the sub and power board .The problem occoured .there is nothing printed out on PC end .I have tested  the NAND,DDR,and UART0,all test passed .when i load the uboot-mim-nand  to the 8148,and i found the problem happened at the start .just as the picture below shows ,it could not jump to 0x81000058. i don't know the reason caused the problem .does i need to modify the uboot files to change the configure abord 8127 to 8148? Are there any differrnces abort the two processors where i hadn't noticed ?

thanks for  your quick reply!

    Hello,

    I am not familiar with DM8127 IPNC, I work on DM814x EZSDK. And I suspect we can not reuse the DM8127 u-boot to the DM8148 EVM as it is.

    Regarding DM8148 EVM, please refer to the below wiki page:

    http://processors.wiki.ti.com/index.php/TI81XX_PSP_UBOOT_User_Guide

    http://processors.wiki.ti.com/index.php/TI81XX_PSP_UBOOT_User_Guide#Building_U-Boot

    As you can see, we need to configure the u-boot (both 1st stage and 2nd stage) with the corresponding command (ti8148_evm_min_nand and ti8148_evm_config_nand for NAND boot) before creating the u-boot with the $ make CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm u-boot.ti command.

    Regards,
    Pavel
