Also MMC (SD card) didn't work for me, I think there was no device detected at all. USB works. This was with chainloading U-Boot, so it might as well be a problem with those devices not being turned off properly and/or the mainline init code not being able to cope with all corner cases (like already initialized devices). All of MMC, USB and SATA work with the Marvell U-Boot version on the SPI flash. Unfortunately I can't do further tests or debugging at the moment (although the build process now seems to work correctly), as I managed to snap off the microUSB socket from my board (while pushing apparently too hard to the SATA cable), so I lost console access and couldn't recover yet. I didn't have success with a 1.8V serial adapter connected to those UART pins on the JTAG header. I will try later to solder a TX and RX wire to the PL2303 chip's pins directly (where I can measure 1.8V in contrast to those JTAG header pins) - but only after my holidays ;-) Cheers, Andre. _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
