Hi,
I tried the microSD procedure and the results are such, that all works well for u-boot-sunxi, but all fails for mainline u-boot. In the later case, i get some endless binary stuff out of the microSD tty line, mostly 'U's and some unprintable chars, while in the first case, i get a proper u-boot(-sunxi) console on microSD tty. Thus for now, I'm stuck there with the device, [[Tristan-Auron-Planet-1]], an A20 tablet, with respect to upgrading to mainline u-boot. I really wonder what this could be. I had no problems booting the tablet with u-boot-sunxi and could use the u-boot-sunxi binary both for this device and for a Lime2 board. I can perfectly boot the Lime2 board using mainline u-boot. Thus, my finding is such, that u-boot issues some difference between the tablet and the board which are not noticeable on u-boot-sunxi. As good as I understand both hardware, it should really behave identical as only the core SoC material is invoked at that time. I tried setting the dram parameters for the tablet as reported by meminfo and removed some extra Lime2 specific stuff from the config but results are still identical. I can still boot the Lime2 board using it, but not the tablet. Also, I tried deactivating vga, usbkbd. No change. I regret for not being able to provide any more specific diagnosis, but hope the effect is somehow familiar. Perhaps there more stuff i should try to deactivate in mainline u-boot? There should be some chance do find the issue by a differential diagnosis. Any suggestions, hints, guesses?
