Hi all,
I have a pw2 serial starting 9017*** which fails to boot completely the screen stays lit.
So soldered a serial cable on and have fastboot working complied from source.
I been at this a few days seem to remember flashing over fastboot something and was asking for login at one point which it does not seem to be for the moment I kind of feel like I walking backwards :blink:
what I can do:
Set up:
on linux: run script logfile.txt
then: screen /dev/ttyUSB0 115200
1. start with serial, no usb then reboot the pw2, interrupt by pressing a key early in boot,
enter uboot: U-Boot 2009.08-lab126 (Apr 23 2014 - 01:01:24)
bist mmcinfo
gives:
2. interrupt by pressing a key later in boot and getting the menu:
letting it continue, with out pressing anything it halts at:
3. sudo ./fastboot setvar bootmode diags_kernel or diags, halts at same place as above
bootmode kernel gives:
4. connected to USB port get the menu above:
Pressing E mounts for about 30s-1m USB the pw2 containing documents and system.
So anyway ... I been at this for a few days, think I should try again somehow flashing the mmcblk0p1.bin, mmcblk0p2.bin, main_kernel.img, diags_kernel.img from kindle_pw2_jb_5.4.0 or something else? can you load MMC over serial :bulb2:
kind of think I going down a long rabbit hole here...:bookworm:
