Glitch in CubeMX RISAF

[Amit_RS]

Dear all I was setting up the RISAF4 for STM32MP257, however, the partition with name "linuxkernel2" has a glitch where its size shows as given

Which is beyond the size of my LDDR4 set to 8Gb.
How to solve it? A quick reply will be appreciated.
Thanking you!

With regards
Amit

Hello @Amit_RS 

Thank you for highlighting this issue on STCommunity.
Could you provide an IOC in order to investigate the issue?

KR, Souhaib

There is lot of confusion:

and here I find lot difference than the generated code which confuses me. This also doesn't match the github code. Which one to follow?

Please answer to this as quickly as possible. Its urgent.

Hello @Amit_RS ,

For information this problem was also reported by your local support and we are investigating it. Internal ticket number : CDM0062070

BR,

[Amit_RS]

There are actually two glitches :
the first one is what I reported. The second one is in RISAB 5 and 6. The same address appears both in RISAB 5 and 6 and hence might cause overlap of memories.

 

Moreover, I have a question that in EV1 device-tree there is no linuxkernel1 and 2 partition. below I have shown the generated device tree by cubeMX and the one from EV-1 Device Tree:
Generated:

linuxkernel1: linuxkernel1@84000000 {
