WikiReader strangeness

[Joachim Pedersen]

Hello all-
OM was very generous!

That being said I like trying to figure out what went wrong with the
original WR...It still randomly flashes one line of horz pixels across
the screen on _most_ power ON events.
So, I've hacked together a nice little 3.3v serial cable, and I'm
talking to the WR over serial. It seems very much alive,
Output:

CPU: C33 PE little endian core  S1C33E07 V 0x21
BAT: 2801 mV

LCD_HEIGHT_LINES  = 208
LCD_WIDTH_PIXELS  = 240

VRAM_HEIGHT_LINES = 208
VRAM_WIDTH_PIXELS = 256
VRAM_WIDTH_BYTES  = 32
loop (space->pause/resume, enter -> exit)

etc... But fails the "Boot Test Program" on all counts:

 Ok

My next step was going to reflash
F. FLASH MBR
I'm assuming that is the firmware on the epson. But I'm getting some
errors when I make flash

mo-lib/mini-libc/include
-I/usr/local/src/wikireader/wikireader/samo-lib/include -c -o
build/analog.o -Wa,-ahl=build/analog.asm33 src/analog.c
src/analog.c: In function `Analog_BatteryMilliVolts':
src/analog.c:111: error: `ADC_SERIES_RESISTOR_K' undeclared (first use
in this function)

Ideas?
thx much!
