Initial steps with p3udl via USB

See https://github.com/linux-chenxing/p3udl

Manually creating the partitions in u-boot

ubi createvol uboot 0x100000 static
ubi createvol env 0x20000 static
ubi createvol kernel 0x800000 static
ubi createvol root 0x2000000 static
ubi createvol rescue 0x1000000 static
ubi createvol data

loady ${loadaddr} 460800;
ubi writevol ${loadaddr} kernel ${filesize}
ubi writevol ${loadaddr} root ${filesize}
ubi writevol ${loadaddr} rescue ${filesize}

Manually booting

mw.w 0x1f207980 0x200; setenv bootargs clk_ignore_unused usbcore.autosuspend=-1 console=ttyS0,115200 ubi.fm_autoconvert=1 ubi.mtd=1 ubi.block=0,root root=/dev/ubiblock0_3 quiet; ubi read 0x21000000 kernel; bootm 0x21000000

Manually updating the rescue image

UBIFILE=perdita-kernel-rescue.fit; cd /tmp && tftp -g -r $UBIFILE 192.168.3.197 && ubiupdatevol /dev/ubi0_4 $UBIFILE

Manually booting the rescue image

In u-boot:

setenv bootargs clk_ignore_unused console=ttyS0,115200 ubi.mtd=1 quiet; ubi read 0x21000000 rescue; bootm 0x21000000#ssd210-picow

To flash another board using a picow:

setenv bootargs clk_ignore_unused console=ttyS0,115200 ubi.mtd=1 quiet; ubi read 0x21000000 rescue; bootm 0x21000000#ssd210-picow#ssd210-picow-snander
