Hi,
Based on the TDA4VM SBL_0806 version of the SDK, I want to implement the SBL enable boot partition before enabling the partition I want to boot based on the configuration file stored on emmc. However, the source logic of 0806 SBL currently conflicts with the function I want to implement. Is there any way to solve this problem?
The following is the source code for SBL:
We have a configuration file stored in emmc, which records the current boot partition number and the partition number where the wrong APP image is located. I will read this configuration information before enabling the boot partition and avoid the wrong partition number where the boot APP is located when enabling the boot partition. However, the emmc had not been initialized before the partition was enabled, so I could not read the configuration information on the emmc.
Hi KONG XIANGXU
Do you want to dynamically switch between the partition?
For Example you will read the configuration file from one partition and based on that configuration you will make the decision to switch to other partition .is my understanding is right ?

Hi,
Yes, that's right. Dynamically switch between boot0 and boot1 partitions based on EMMC_BOOT0.

Hi Kong,
Apologies for the delay.
Please refer to the patch 0001-.-boot-keywriter-main.c-Add-capability-to-switch-eMM.zip
This patch is for dynamically switching partitions in key writer. You can refer to this patch to add the same functionality in SBL.
