Hello https://community.nxp.com/t5/user/viewprofilepage/user-id/4760,

do you know if the patch will be included in the standard BSP?

Is it availble an update patch for 6.12.34_2.1.0?

Pls. let me know if the DDR on the board is DDR5 or DDDR4.

Hi @StefanoGattazzo 

Do you  get any issue to try the patch on 6.12.34_2.1.0? I think it is close to 6.12.20.

Hi qiang_li-mpu_se,

I asked in advance before test.

 

BR

Stefano
