Flash dvr rdk on DM816x board

Vikas Ramesh

I was trying to flash the pre built binary from <DVR_RDK_install_dir>/pre_built_binary/ti816x_evm using the mksd-ti81xx.sh from <DVR_RDK_install_dir>/ti_tools/linux_lsp/collaterals/collaterals/host-tools/mksd-ti81xx.sh.

According to this http://processors.wiki.ti.com/index.php/TI81XX_PSP_UBOOT_User_Guide#Setting_Up_Boot_Environment_on_SD_Card, the script requires
<tar.gz filesystem> but we have ubi_128_DM816X_TI_EVM.img file in the prebuilt binary. So flashed that one only to the SD card and tried booting the board. It did not work.

It gave the following error

U-Boot 2010.06 (Oct 23 2013 - 12:13:34)

DRAM: 2 GiB
MMC: OMAP SD/MMC: 0
Using default environment

Hit any key to stop autoboot: 0
** Can't read from device 0 **

** Unable to use mmc 0:1 for fatload **
## Starting application at 0x80800000 ...

I also tried to flash the nfs filesystem present in <DVR_RDK_install_dir>/target/* folder to the SD card. This also gave the same error when I tried to boot it up.

Can anyone please help me solve this?

What is the DVRRDK version you are using ?

Does boot from nand work or does that also fail ?

The dvr rdk version is DVRRDK_04.01.00.02.

I tried to flash to NAND from SD card and when i did

TI8168_EVM# mmc rescan 0

it gave this error
raise: Signal # 8 caught

are you trying to use NAND flash filesystem on MMCSD? If you are starting with a board that doesnt have bootloader flashed on it, you need to flash the bootloader image first. In the MMCSD case above the init scripts are trying to autoload the kernel and filesystem.

You first need to choose if you want to use MMCSD or NAND for bootup.

To boot from NAND:

1. You need to burn the bootloader, kernel and filesystem images on NAND. You can do this from the uboot command prompt

2. If you do not have uboot running on the board, use Ethernet or SD boot mode to load Uboot.

3. Flash the images on NAND, following instructions from here:http://processors.wiki.ti.com/index.php/TI81XX_PSP_UBOOT_User_Guide#Transferring_images_to_NAND_via_U-Boot

If you want to boot from SD card, follow instructions from here:
