Linux的/ TDA2EG： Linux的/ TDA2EG：vision SDK 3.02 with earlyboot late-attach problem, spl still read u-boot.img

Hi,

The error during make linux_install is due to a missing file. Please check the installation of Vision-SDK once again. The file
'vision_sdk/apps/src/hlos/modules/sgxRenderUtils/Tools/OGLES2/
Build/Linux_armv7hf/ReleaseNullWS/libogles2tools.a'
is included in the installer.
The error in make linux_install is that the above mentioned file can't be found.
After make linux install is complete, create a bootable SD card.

The MLO will try to jump to u-boot.img. However, on single-stage boot there is no u-boot.img in the boot partition, so the MLO jumps to the kernel (uImage), which exists in the boot partition. The error noticed during make linux_install isn't related to MLO jumping to u-boot.

Please increase the loglevel in the kernel device-tree, this will provide details on where exactly the kernel initialization fails. To increase the loglevel, update 'loglevel=8' in the 'chosen' node of the device-tree (arch/arm/boot/dts/dra72-evm-infoadas.dts) and rebuild Linux.

I think MLO still not jumped to kernel,

so, there is no log information, even if I have adjusted the loglevel to 8,

Which modification is to let MLO automatically jump to the part of the kernel,
or is this the original program?

My configuration is as follows,

Hi,

The parts of early-boot-update.sh in my version(3.02) is like below,

so dsp and ipu filename extension  should be .lzop ?

my sd card boot partial is like below,

but MLO still not read iImage ....

In addition, I have seen the configuration of single stage or falcon,

Just like this link,

https://e2e.ti.com/support/arm/automotive_processors/f/1021/p/618773/2280079

is that Earlyboot  supposed to do the same setting with my visionSDK version and board ?

Hi,

i followed your steps,

the spl still not reads uImage.

i traced spl code,

found that spl_load_image_ext() in spl_ext.c

err = ext4fs_mount(0);

lead to failed to mount ext2 filesystem...

is that the part for reading uImage?

Hi,

Can you confirm you're running on production SD boot mode? As indicated in the previous post, please set the boot-setting to

SYSBOOT [ 0:15 ]: 00001100 10000001

Can you also confirm you've run the commands 'env default -fa' and 'saveenv' after halting at u-boot?

After running the above commands, please run the below command on u-boot and paste the output. 

=> printenv

Can you also try creating another SD-card and see if it boots?

Regards

Shravan
