Hi

Thanks for confirming the condition.

We tried that with the latest uboot branch of QPDS24.3.1_REL_GSRD_PR and we dont see the problem.

I see that the SPL and Uboot is of different version in your logs.

Could you try using the uboot branch QPDS24.3.1_REL_GSRD_PR?

I tried that and managed to access the remaining 6GB in reserve.

Regards

Jingyang, Teh

      Hi,

      Can i know what kind of file do you used to write in DDR.

      Do you transferred the file from DDR to mmc?

      If transferred what kind of file you used and from which memory region you used.

      Please confirm the above details ASAP.

      Thanks,

      M Gokulraj
