I am running on a custom board and have been bedeviled by the behavior where I can boot off a SD Card with the SPL loading U-Boot also off the SD Card for many new build / copy to SD Card / boot iterations and then it stops with an error message that the SD Card did not respond to the voltage select command. Adding debugging printouts indicate the SD Card does not respond to commands right at the start of the capabilities read operations for no apparent reason. Once it fails for a given image, it always fails for that SD Card until I load a new image... then it might work or might not. Sometimes if I reformat the SD Card it works again (presumably due to shifting where the images are on the SD Card), sometimes not. This has been driving me CRAZY. I've applied your changes and will see if my problem goes away, but it is a "halting problem" in that I don't know how many time it has to succeed before I'm sure it will never fail. :-/ Thanks, gvb _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
