HP-30B Fun (HP-45 Simulator...) Message #1 Posted by svisvanatha on 16 Feb 2011, 10:33 p.m. Cool ! With the cable that Tim sent, I was able to flash the HP-30B with the HP-45 simulator. Video of HP-30B running HP-45 Simulator HP-45 Software Demo

Re: HP-30B Fun (HP-45 Simulator...) Message #3 Posted by svisvanatha on 17 Feb 2011, 9:39 a.m., in response to message #1 by svisvanatha My next step will be to locally compile my own binary of the HP-45, and successfully load that. The demo I showed was with the pre-built binary from the 20B wiki. Once that is done, then I will take the leap with the wp-34s. I saw in another post it was mentioned that it was not ready for deploying to the hardware - is that still the case? Edited: 17 Feb 2011, 10:15 a.m.

Re: HP-30B Fun (HP-45 Simulator...) Message #4 Posted by svisvanatha on 20 Feb 2011, 11:25 a.m., in response to message #3 by svisvanatha Have spent some time trying to build the hp-45 demo in Ubuntu. I can successfully compile the binary with CodeSourcery, but it does not flash into the device with sam-ba (from WinXP). Incidentally, I cannot get one environment to work with both CodeSourcery and Sam-ba. In Ubuntu, I cannot get sam-ba to show the dialog that you use to select the BIN image. And in WinXP, Sam-ba works fine, but I am not sure how to compile with CodeSourcery! I should perhaps stick to Aircraft Engineering ! Any tips on either getting sam-ba to work in Ubuntu, or what to do with CodeSourcery in WinXP? Many thanks.

I did most of the dev work with the CS (or was it the RTEMS?) tools under win2k. I did check the build with a scratch built gcc cross compiler under openbsd/sparc64, so it should be fairly portable. I've got a x86 VPS running Debian, which should be close enough to your Ubuntu--I'll try and test it out today if I get a chance.

Re: HP-30B Fun (HP-45 Simulator...) Message #6 Posted by svisvanatha on 21 Feb 2011, 2:08 a.m., in response to message #4 by svisvanatha Thank you for the reply. Some further information. I have now managed to use both CodeSourcery and Sam-ba from within WinXP. I was missing the fact you had to use 'cs-make' to make the project. 1. I compiled demo_45 from source using cs-make from within WinXP. This gives a bin file of size 16772 bytes. That does not match the size of the bin file (i.e. 16896 bytes) from the demo_45 tar.gz archive . 2. There was one warning in the compile process, in line 533. 3. The 30B does not turn on after following the usual flashing procedure with this bin file.
