[wp34s] xtal question Message #1 Posted by jerome ibanes on 3 Feb 2013, 12:51 a.m. My WP34s didn't survive the last flash, probably due to some fault of mine. This one had a crystal, but I don't intend to open a 30 to make a 34; so not adding a crystal would only remove the internal clock or would anything else be missing too? Thanks!

Plus no printing support but you likely didn't have that anyway. You should be able to recover a bad flash -- just go through the process again. - Pauli

Re: [wp34s] xtal question Message #6 Posted by Marcus von Cube, Germany on 4 Feb 2013, 2:39 a.m., in response to message #4 by jerome ibanes Does MySamba tell you it can't send? If so, does it take a second or so to tell you or is the error message instantaneous? The latter would mean that Windows has a problem with your serial port, the former is related to the calculator. You should measure the voltage of the batteries. SAM-BA boot mode drains them quickly and you don't see it in any way. If the batteries are good and you're sure the chip is in SAM-BA mode pressing ON on the calculator for a second or two should bring it into accepting a connection from MySamba. If you can flash but you cannot start the calculator afterwards this may be related to the xtal modification. Try ths default image cal.bin (or calc_full.bin) instead of the xtal build.

The batteries' voltage is, respectively, 2.84V and 2.82V. Most unfortunately I do not own a windows computer, I'm using wp34sflashcmd on linux/x86_64. The USB port is properly seen by the host, but wp34sflashcmd timeouts as unable to find the calculator, despite the erase/reset sequence. I may be able to ask for access to a windows machine at work, if you think this might help. Thank you for your help.

Re: [wp34s] xtal question Message #9 Posted by jerome ibanes on 5 Feb 2013, 5:28 p.m., in response to message #8 by Walter B Quote: Buenas dias, Jerome, Hola. I requested a windows machine from work (those are getting harder to get by these days) and I was able to flash the wp-34s, it didn't work with the ftdi cable, but that same machine had a serial port, and it worked this way. Now my wp-34s works again, thank you all! On a side note, the keyboard stickers are scratched to hell (my fault), is there any place that sells less scratch-able ones? I got mine from hpcalc. Granted, I should pay more attention to my "hp".
