Tool/software:
Hi，team
We download the latest SDK10_01 and want to verify PCIe functions based on this version. But follow the user's guide 3.1.1.5, we can not boot Linux from emmc.
Has this guide been upgraded to 10_01? Could you provide more detailed operation steps？
Regards,
Mingjian Shang
Hi, Gokul
Yes, we are using custom board. We boot SDK09_00 Linux kernel from emmc successfully with TDA4 Flashing Techniques guide. Our hardware does not change but failed to boot SDK10_01 Linux kernel. It seems that there are diffs between the SDK rather than hardware.
Besides, we noticed that sysfw.itb does not exist in SDK10_01. We want to know if this guide is still effective. If not, please give us some support.

Mingjian
Hi Mingjian,
Sorry for the late reply.
Yes, we have.
Can you follow the steps below,as it worked for me following these steps as the size for the 10_01 SDK:
Step 1:Follow the steps below,with seek = 200 instead of 100 as the tinyrootfs image size has increased in this SDK.
Also use sudo while executing the mkdir command.
Step 2: Once the above steps(ie:tinyrootfs has been copied) are done , execute the sync command to ensure that the cache is flushed.T
Step 3:
Step 4: Now follow the below steps to flash these images to emmc using DFU-UTIL.
Note: Once the sudo dfu-util -a rootfs ..... command has been completed,just do sync in the host machine.
Step 5:Halt at the uboot stage after switching to emmc boot 0.
Step 6: After entering into U-BOOT,execute the following commands:
setenv mmcdev 0
setenv bootdev 0
setenv bootpart 0
boot
