Hello,
I'd like to know if exists a method to store in eMMC a bootolader without kobs-ng, so without using linux, but simply running a command from u-boot. I booted my i.MX28 system (I have the same question for i.MX6 as well) using the u-boot.sb (u-boot-2015.01 with SPL) file loaded with mxsldr (or imx-bootlets). Now I am trying to save it in eMMC with the following command loady (load u-boot.sb with ymodem) mmc write ${loadaddr} 0 ${filesize} but at reboot nothing happens. Is it possible?
You should flash u-boot.sd, not u-boot.sb.
Please check doc/README.mxs on how to generate u-boot.sd.
Hi Fabio, I did the following steps on the host $ make u-boot.sb $ ./tools/mxsboot sd u-boot.sb u-boot.sd
then in u-boot
loady (load u-boot.sd with ymodem) mmc write ${loadaddr} 0 ${filesize}
but at reboot no output on serial port. Maybe do I need to format the eMMC before?
Thank you -- Marco
