Uboot install on PogoplugPro V3 question
January 19, 2021 10:48PM
Hello. I just picked up a Pogoplug Pro that is still stock. I'm wanting to set up the Bodhi uboot and rootfs. I'm following https://forum.doozan.com/read.php?3,16017 and it says /proc/mtd should look like this:

Quote

dev: size erasesize name
mtd0: 00e00000 00020000 "boot"
mtd1: 07200000 00020000 "data"

However, mine looks like this:

Quote

root@PogoplugPro:/tmp# cat /proc/mtd
dev: size erasesize name
mtd0: 08000000 00020000 "NAND 128MiB 3,3V 8-bit"
mtd1: 00e00000 00020000 "boot"
mtd2: 07200000 00020000 "rootfs"

I remember on my Pogoplug V4 this is set with the mtdparts env variable, but there is no mtdparts variable on this V3 pogoplug.

How do I fix this on a PogoplugPro V3?

That's OK. They are the same. It's an overlay mtd0 that is basically the whole NAND space. mtd1 and mtd2 are inside mtd0 in this layout.

The u-boot installation only deal with mtd0. So it will be correct.

Later, after booted into Debian, you can adjust the mtdparts definition.

OK, thanks. Yeah, that worked fine.

I also enabled stock recovery environment, as described at https://forum.doozan.com/read.php?4,22570,22570#msg-22570, but did it slightly differently. I changed the "run load_uimage" in bootcmd_exec to "if run load_uimage; then", and added an "else" at the end to run bootcmd_stock, like this:

Quote

bootcmd_exec=if run load_uimage; then if run load_initrd; then if run load_dtb; then bootm 0x60500000 0x60e00000 0x62c00000; else bootm 0x60500000 0x60e00000; fi; else if run load_dtb; then bootm 0x60500000 - 0x62c00000; else bootm 0x60500000; fi; fi; else run bootcmd_stock; fi
