WP 34S Owner‘s Manual  

Edition 2.2 

Page 94 of 103 

 

APPENDIX A: SUPPORT FOR FLASHING, SERIAL I/O ETC. 

How to Flash Your HP 20b or 30b 

You  may  do  the  flashing  yourself.  Then  you  need  your  calculator,  a  special  connecting  cable, 
and  specific  software  on  your  PC  or  Mac.  A  PC  featuring  an  hardware  serial  port  and  running 
Windows  XP  is  beneficial. 

Please  read  this  paragraph  completely  before  actually  starting 

the procedure.

  

  You will get the necessary software 

– the SAM-BA In-system Programmer – here for free: 

http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3883

 

Install it as explained by Atmel.  

  You may get the cable from Gene Wright.  

  The specific file you will need to transmit to your calculator to make it your WP 34S is called  

calc.bin

  

and is included in the zipped package you can download from here: 

http://sourceforge.net/projects/wp34s/files/

 

Alternatively, you may download  

calc.bin

  

alone from 

http://wp34s.svn.sourceforge.net/viewvc/wp34s/trunk/realbuild/

 

Now,  having  got  these  three  (SAM-BA,  the  cable,  and 

calc.bin

 )

,  please  turn  to  the  file 

http://dl.dropbox.com/u/10022608/Flashing%20a%2020b%20Calculator.pdf

 

(edited 

by 

Tim 

Wessmann and Gene Wright). Read it thoroughly for information about connecting and flashing. 

ATTENTION:

  If  your  PC  does  not  feature  an  hardware  serial  interface,  you  will  need  an 

USB-to-serial converter to connect the special cable to your PC. Following our experience, 
converters containing FTDI chips will work 

– others may not. 

On other operating systems than XP flashing may work or not (definitively not on Windows 
2000 or earlier). Please check. 

On Windows 7 load MS Windows Virtual PC and Windows XP Mode, then work therein. 

Then proceed as described in 

Flashing a 20b Unit

 in said file, steps 1 to 3 only. 

ATTENTION:

 Flashing  your 

HP 20b

 or 

30b

  will  erase the HP firmware in step 3,  meaning 

your business calculator will be gone then. The firmware will be replaced  with the WP 34S 
file completely! After this flash is finished, you will have a 

WP 34S RPN Scientific

 

– i.e. your 

calculator will react as documented in this very manual. 

This also means your device  will not do anything useful for  you  between step 3 and 13. It 
may even look dead 

– it is not, be assured, at least it will just be eating your batteries (see 

below)! If you (have to) interrupt the flashing process at any time in this interval for any rea-
son  whatsoever

, don‘t  worry: simply start again. You may, however, not get any feedback 

displayed in step 3 anymore. That does not matter, just stick to the procedure. 

As long as the cable is connected to your calculator, it will draw a considerable current from 
the  calculator  batteries.  If  you  happen  to  hang  anywhere  in  the  flashing  process,  also  the 
processor  is  left running  at  full  speed.  So  chances  are  high  your  coin  cells  will  be  drained 
while you are trying to find out what is going wrong. Thus it is wise to disconnect the cable 
from your calculator when you will not need the cable for the next couple of minutes. For re-
peated flashing, an external 3V DC supply may pay very fast. Take care to c to the 
outer and 

– to the inner contact. The following will work with a good 3V supply only.
