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. :-( Does barebox building this kinda of image? I see under the images folder, a file named: start_imx6_[BOARD].pblx.imximg but as far as I can see, this file is the same as the barebox-[BOARD]-imx6q.img... The Reference Manual in the Boot Section does not explain well on HOW TO PREPARE a MICROSD card just to be sure the DCD and other stuff (like PBL) have to be written just to bootstrap from microSD/MMC... Can anybody help me out on this?
