I'm using a custom board equipped with a RoadRunner from Acmesystems (based on a SAMA5D27 SoC) with 256 MB of RAM and 16 MB of QSPI memory. I have an issue with the SD Memory : I'm unable to use a HC / UHS-I SD memory card, where a classic SD works. There is the state of the art :
My at91bootstrap (with boot directly linux option), my kernel (v. 4.9.81) and my DTB are on the QSPI memory. The configuration is : at91bootstrap loads the kernel and the DTB in memory and launch this command line :
