Hi All, 

We are using OSPI NOR Flash S28HS512TGABHM013 in our product. It would be great if you can share compatible driver for Linux-5.10.35 version. 

Hardware Platform: i.MX8QM 

Best Regards

Hello Vabu,

Thank you for your patience. The S28HS512T support was added from Linux-5.11.

For Linux-5.10.xx, please apply the following patchset.

Dear Bushra, 

After integrating patches, we could not see the NOR flash detected in the kernel debug logs.

root@root:~# dmesg | grep -i spi
[ 0.000000] GICv3: 512 SPIs implemented
[ 0.000000] GICv3: 0 Extended SPIs implemented

Please let us know if you have any debug mechanism or different power up sequence for Semper NOR Flash.
