Hello everybody,
first of all, I would say a BIG thank to everybody point me out on have
a USB-Serial Downloader working and Barebox up and running in my custom
iMX6Q based board.
Right now I wish to know what can be done or not done to fireup the
board from attached microSD card which is working because Barebox (from
USB Downloader) is seeing it and find any partition scheme found on it.
If I simply write the barebox-flash-image (currently a symlink to
image/barebox-[BOARD].img file) to a sdcard with command:
[my usb-adapter is seeing the sdcard as /dev/sdk]
dd if=barebox-flash-image of=/dev/sdk
it works, but actually I have lost all MBR partition scheme at all.
I read somewhere (https://community.freescale.com/docs/DOC-95015) that
writing the .imx file with an offset of 1K from the beginning of the
card it should run.
Actually it is not. :-(
I can answer to this by myself ;-)
The issue is to write skipping the fisrt 1024 of the sdcard (bs=512
skip=2 and skipping the first 1k from the image itself [seek=2])
dd if=barebox-flash-image of=/dev/sdk bs=512 seek=2 skip=2
works fine.
Sorry for noise.
;-P
