|trouble flashing wp34s under Linux|
Message #1 Posted by Glenn Becker on 18 July 2013, 8:41 p.m.
After a long wait, I tried tonight to flash my wp34s (HP30b type) with the release from 3-7-2013.
So far I have had no luck getting past "Cannot connect to WP34s". I'm using a laptop running Slackware Linux 14.0 with a docking bay (w/serial port on it) connected via a USB port. I'm assuming (maybe a bad thing) that the serial port I'm trying to connect through is /dev/ttyUSB0.
I first run setserial and get the following:
# setserial -G /dev/ttyUSB0
# /dev/ttyUSB0 uart 16654 port 0x0000 irq 0 baud_base 460800 spd_normal
... which, I guess, looks okay to me. Then I run
./wp34sflashcmd ../wp34s/real/calc_xtal_full.bin /dev/ttyUSB0
and get the "Cannot connect" message.
After searching the message board I did find a recommendation that I press RESET and then ON before flashing, so I tried this. Curiously, I do not get the expected click when I poke a paper clip into the 'RESET' hole, so I don't know whether the reset is somehow fouled up, or what. I've removed the three screws from the back of the unit to see if I could pry it off and scope out what might be wrong with the reset button, but so far I've had no luck getting the thing to come apart.
So currently I have a dead HP30B/wp34s. If anyone can suggest a reasonable next step, I'd be happy to try it. I could perhaps try connecting under a different flavor of Linux.
