Performing POST in U-boot for imx8mm

[Jarvis3345]

Hi Team,
Iam currently trying to perform a POST(power on self test) in uboot which includes ram test ,watchdog test and L1 cache of imx8mm.
For ram test iam writing and reading back the sam pattern form the last 1MB of ram address.
Below are my queries:
1.How can i know the sector size of the ram in order to perform this operation.
2.How can i test the L1,L2 cache of my processor.

Hello,

None of these option work on current implementation of uboot, so please let us know when you have finished.

Hi,
I have already implemented the ram test by performing some read write operations but need more information onto the ram page size, is there a way to test the L1/L2 Cache and if possible watchdog timer.
