Hi, Thanks to Markus Reichl, I got an Odroid U3 to work with. Thanks to Peter Chen, we got a power sequence generic library which solves my long standing Odroid U3 problem - no LAN9730 if it was enabled by bootloader. My previous attempts for this can be found here [0]. This patchset is based on Peter's v11 of power sequence [1]. Patchset is available also on my Github [2]. More detailed analysis is described in patch 2/4 ("ARM: dts: exynos: Fix LAN9730 on Odroid U3 after tftpboot").[snip] On which u-boot should this be tested. On HK u-boot tftp boot is not supported.... so you gave an answer: you cannot test it on HK. How many other U-Boot flavors you know? :)
u-boot mainline have tftp support enable, so I will try to test on this u-boot. Best Regards -Anand
Best regards, Krzysztofquoted
