I remember having seen similar problems when I tried using the eMMC last year. I also used crochet and the copy script, but IIRC ended when it didn't boot. Details should be on this list somewhere. > > Am 11.03.2015 um 08:31 schrieb Emmanuel Vadot <elbarto@bocal.org>: > > > > If you have all C it means that the SoC can't find the MLO or that the MLO can't find u-boot.img I don't remember which one. > > > > -- > > Emmanuel Vadot > > > >> On 11 Mar 2015, at 08:27, Hellmuth Michaelis <hm@hellmuth-michaelis.de> wrote: > >> > >> Hi, > >> > >> i???m running a recent current on a beaglebone black and i???m using crochet to build stuff. I???ve seen the copy to eMMC script in root and tried that. After running it, i checked the MSDOS and UFS partitions and it seems they are OK. But, after removing the SD card and trying to boot from the internal eMMC i just see ???C??????s coming out slowly of the serial console, nothing else is happening. Putting in the SD card and all runs well again. > >> > >> Has someone a hint what to look for to get it working ? -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
