rd to follow why the DM now is essentially enforced for storage media but does not seem to be tested with SPL. Once again, I appreciate any pointer to a possible solution. Rudi On 5/18/20 4:45 PM, Rudolf J Streif wrote: > I have a custom board that is similar to the i.MX6UL 14x14. One > di

U-Boot DM device tree and Linux device tree - what are the differences and why?

2020-05-18 Thread Rudolf J Streif
I have a custom board that is similar to the i.MX6UL 14x14. One difference is that it has an eMMC rather than a SD card. Most recently I upgraded from u-boot 2019.07 to u-boot 2020.01 and now u-boot cannot detect the eMMC anymore. For the 2019.07 version I did use CONFIG_FSL_ESDHC=y without CONFIG

[U-Boot] U-Boot Support for SIL3531

2016-11-01 Thread Rudolf J Streif
Does anyone know if u-boot supports the SIL3531 PCIE SATA controller? drivers/block/sata_sil.c explicitly lists SIL3131, SIL3132, and SIL3124. I am not that familiar with the history of the SIL SATA chips and maybe somebody knows if the SIL3531 is backwards compatible to those chips. Thank you,

[U-Boot] Copy to Flash... 9Flash not Erased
