Devuan installer can't start on MX53 Loco (i.MX53 Quick Start board)


I have a "i.MX53 Quick Start board", which named "MCIMX53-START-R" (a new one, with PMIC MC34708 and Device tree file "imx53-qsrb.dtb", not old board with PMIC Dialog DA9053).

I repeated steps from … ble_images:

 % wget "
 % wget ""
 % zcat firmware.MX53LOCO.img.gz partition.img.gz > complete_image.img

Here are sha256sum(s):

fdb1096a90394878f0f5e23e146cc89ecd55d867b4b9327b791112041d8c9f51  complete_image.img

f3cf86ab65a1ca2469ca9fe9fe7ac1e9267d3c69bc5f12c7131503bb5e5764ca  partition.img.gz

And some other info:

 % file firmware.MX53LOCO.img partition.img complete_image.img
firmware.MX53LOCO.img: DOS/MBR boot sector; partition 1 : ID=0xc, active, start-CHS (0x0,32,33), end-CHS (0xc,114,38), startsector 2048, 197952 sectors

Some useful information from U-Boot console, when I loaded board with this image:

=> printenv

I wrote image to SD card:

 % sudo dd of=/dev/sdb if=complete_image.img bs=4M status=progress

24+1 records in
24+1 records out
102400000 bytes (102 MB, 98 MiB) copied, 18,5083 s, 5,5 MB/s
The problem

I powered on my "i.MX53 Quick Start board" with SD card with Devuan installer:

U-Boot 2019.01+dfsg-7 (May 14 2019 - 02:07:44 +0000)

Non-mainline u-boot or old-style mainline u-boot detected.
This boot script uses the unified bootcmd handling of mainline
u-boot >=v2014.10, which is not available on your system.
Please boot the installer manually.

As I understand, "Warning - bad CRC, using default environment" is OK.

U-Boot not installed inside board, it run from SD-card, from Devuan file "firmware.MX53LOCO.img".
The file "boot.scr" also came with Devuan image, "partition.img".
But they don't want to work together.

Any ideas how to fix error "Please boot the installer manually"?

Re: Devuan installer can't start on MX53 Loco (i.MX53 Quick Start board)

Installer started after some manipulations (I'm not sure about addresses, especially kernel_addr_r=0x70008000):

=> setenv distro_bootpart ${mmcpart}
=> printenv distro_bootpart         
=> setenv boot_targets mmc
=> printenv boot_targets
=> setenv fdtfile ${fdt_file}
=> printenv fdtfile
=> setenv bootpart ${mmcpart}
=> printenv bootpart
=> setenv devnum ${mmcdev}
=> printenv devnum
=> setenv console ttymxc0
=> printenv console
=> setenv devtype mmc
=> printenv devtype  
=> setenv fdt_addr_r ${fdt_addr}
=> printenv fdt_addr_r                                    
=> setenv ramdisk_addr_r ${loadaddr}
=> printenv ramdisk_addr_r          
=> setenv kernel_addr_r 0x70008000
=> printenv kernel_addr_r
=> boot

Problem 2: ISO image

What have I do here?

Which ISO image to use? I tried … t/mini.iso — it is too small, only 33MB, and error is the same.

Re: Devuan installer can't start on MX53 Loco (i.MX53 Quick Start board)

hello vazhnov,
For what I see it seems that you had done it correctly,
But the hd-media type expects a different image type( with the contents of installation.. ) sad

I advise you to go with the netboot-install version,
Since the media image comes from the repos, and its usually the method less prone to errors..

I believe you have followed this instructions:
when dd'íng the image use a 'conv=sync'..

In that url, you will find Installable netboot Images, go to the correct place, and download the correct ones for you.. … ard-images smile
