OK, update. While I did let the magic smoke out of the 2v uart I bough, I was able to use a 3.3v uart from my other device to read the TX pin.
I'm not prepared to try to hook that up to the RX pin, all the warning about burning out the kindle too for over voltage :-)
But I though it would be fine for reading from the kindle.
So without the screen, it boots up, and the last line before a kernel dump is:
Code:
[ 0.530360] Bad flash signature: 0x0
Press [ENTER] for recovery menu... 0 /
=== kernel printk buffer (23556 bytes) ===
It then moves into a progress bar type thing that looks like this, but much slower, I only waited about 15 seconds, because I have to manually hold the probe on the TX pin:
On the boot log with the screen plugged in, this is instead where it asks
Code:
Press [ENTER] for recovery menu... 0 //dev/mmcblk0p4:
CHS=4/16/99776 size=3269459968 bytes
flag type first last lba first lba size
Partition p1:
0x00 0x0b 16 <large> 16 6385648
CHS: 0/1/1 - <large>
Partition p2:
Partition p3:
Partition p4:
BOOTING DEFAULT.
So my next step if I keep working with this will be to get another 1.8v chip, and see if I can connect to RX and TX at the same time, and actually interrupt one of those boots.
