Hi WabG,


I not able to confirm about the particular MSEL thing. By default, simply booting up from qspi or sd card, we dont purposely do any changes to the MSEL settings, the FPGA configuration still can be loaded with quartus programmer or using FPGA load cmd in Uboot. I suggest working with the default working settings then only try to make the changes in order to see if that affects the FPGA configuration load operation.


Thanks.

Regards,

Aik Eu

Aik Eu,

I have tried to load the FPGA from UBoot with the good and wrong MSEL setting: as described in the FPGA Manager only the good MSEL allows the configuration.

The control register description of the FPGAManager "Controls whether the FPGA configuration pins or HPS FPGA Manager drive configuration inputs to the CB." must not to be interpreted as the MSEL setting are bypassed with this register.
