Dear support,

 

Could you clarify which compilation options are required to generate SCFW (as describer in imx_scfw_porting_kit_1.2.2), to match scfw-tcm.bin as fetched from NXP during Yocto build ?

 

Currently we face different behaviour during linux start on IMX8QXPMEK board:

A/ With default scfw-tcm.bin file (as fetched June 11th through YOCTO):

linux boot success (tycally can run graphic demos).

 

B/ with regenerated scfw-bin from imx_scfw_porting_kit_1.2.2 package:

linux boot failed during starup, complaining about access to graphic resources

 

I can provide you with detailed serial traces on both UART0 and M4 UART.

 

best regards,

Laurent
