Hello list,
I have a annoying problem with u-boot 2019.07. I try to boot a Linux Image from a fat16 partition on a SD-Card. But I got the "Error reading cluster" Message from fs/fat/fat.c
=> boot switch to partitions #0, OK mmc2 is current device Error reading cluster ** Unable to read file Image **
this error occurs especially on this Swissbit SD-Card (industrial card)
=> mmcinfo Device: FSL_SDHC Manufacturer ID: 5d OEM: 5342 Name: L1BM1 Bus Speed: 50000000 Mode: SD High Speed (50MHz) Rd Block Len: 512 SD version 3.0 High Capacity: Yes Capacity: 3.7 GiB Bus Width: 4-bit Erase Group Size: 512 Bytes
another San-Disk SD-Card (consumer) I tried is working fine with same u-boot image. So it looks for me for a wired hw/timing issue.
