To flash the bootloader, use the following command: cfimager -f eboot.sb -d
I am not sure what is wrong with the original approach - this is what is described in the cfimager notes: Following a reset (and reconfigure to SD boot mode) the system booted up correctly.
Using the mfgtool I connected to the board via the USB recovery port then used the tool to load the WCE image and eboot. Instead of using cfimager to load eboot then drag/drop nk.bin to the SD card I tried using the mfgtool instead. I finally managed to get my WCE image to run. Could nk.bin then be deleted while wince is running? Is it definitely ok to just put the nk.bin on the SD card fat partition? For a system release I am not sure if this would be a good idea. I will keep looking but I hope someone has had a similar experience trying their own WCE image on the i.MX28. The image read from SD seems to jump straight to 100%, followed by 'download successful' then hangs as above, randomly outputting battery voltage. I managed to reduce my image size to 29MB to test (only had an nk.nbo in the release folder this time) however the system still does not boot, even with this smaller image. I noticed that I too had an nk.nb0 and nk.nb1 hinting that I had exceeded the allocated RAM image size. They found that their nk.bin was larger than the allocated RAM in the bootloader. What have I done wrong to prevent the system booting up correctly?Īfter a bit of investigation I found someone else with a similar problem. INFO: Copying NK image to RAM address 0xa0200000ĭownload successful! Jumping to image at 0x0 (physical 0x40200000). INFO: Reading NK image to SDHC (please wait). Press to launch image stored in SD/MMC or to cancel. So far I have performed the following steps:ġ) Built a CE image using the Freecscale BSPĢ) Used cfimager to put eboot_ivt.sb onto my 2GB SD card using the -a option to create the FAT partitionģ) Manually copied NK.bin from my release directory (33-34MB) onto the SD cardĤ) Put the SD card in the dev board (boot switches on 1001) and watched eboot debug output (freescale logo appears)ĥ) Pressed space to stop boot and configured eboot to boot from the SD card (and saved settings)Ħ) Reset the system. I have been playing with the i.MX28 development board but I am struggling to get my own SD card to boot my own CE 6.0 image.
