Because of the S3C2410 bug (INT_SRCPND_RTC not set on alarm wake-up), the firmware need to check on power-on if an alarm is triggered by comparing the alarm date to the system date. But, It failed because the firmware read a system date that is 1 second behind the alarm date, while the cpu was waked-up by an alarm. This is because x49gp uses 2 different functions to read host system time in 2 key routines, leading to a 1 second gap when used consecutively. This fix solved this issue. |

Additional note: August 22, 2013
Updated this so that it'll compile on Ubuntu 12.04.

Quick Start Guide 04/25/2010 Egan Ford egan@sense.net
NOTE: READ ALL INSTRUCTIONS
Prereqs:
-
OS/X 10.6 64-bit:
- Install X11, Xcode (from your installation media) in that order.
- Install Macports (macports.org), then:
sudo port install gtk2 sudo port install pkgconfig
-
Ubuntu 9.04 32-bit, 9.04 64-bit, 9.10 32-bit, 9.10 64-bit:
sudo apt-get install libgtk2.0-dev sudo apt-get install subversion
-
RedHat/CentOS 5.4 64-bit, Fedora 12 64-bit:
sudo yum install subversion gtk2-devel
Start up X11 and use xterm
Download x49gp source:
svn co http://x49gp.svn.sourceforge.net/svnroot/x49gp x49gp
Edit FIRMWARE (optional):
The default firmware will be 4950_92.bin, for HPGCC3 development copy 49_hpgcc.bin in to x49gp and change FIRMWARE in the Makefile.
Build:
cd x49gp make make sdcard make config
Mount SD card:
OS/X:
open sdcard.dmg
Linux:
sudo mkdir -p /Volumes/X49GP/ sudo mount -o loop sdcard /Volumes/X49GP
Put stuff in SD, e.g.:
OS/X:
cp BACKUP /Volumes/X49GP/
Linux:
sudo cp BACKUP /Volumes/X49GP/
NOTE: If using HPGCC2 don't forget the the ARMToolbox.
Eject SD:
OS/X:
hdiutil detach $(df | grep -i x49gp | head -1 | awk '{print $1}')
Linux:
sudo umount /Volumes/X49GP
Run:
./x49gp config
Where's the key labels?
Good question. This is a bug when compiled for 64-bit platforms.
Hack:
cp hp50g-hack.png hp50g.png
Do stuff, e.g.:
Restore backup:
BACKUP 3 ->TAG RESTORE
Install ARMToolbox (HPGCC2):
2 SETUP.BIN 3 ->TAG RCL EVAL (Right Click ON, Left Click C)
To Exit Emulator
- ctrl-c to exit (from launch window)
Start Over:
- clean slate?
rm -f flash-49g+ flash-50g flash-noboot sram s3c2410-sram make flash-49g+ flash-50g flash-noboot sram s3c2410-sram ./newconfig
- soft reset only?
./newconfig
Known Limitations:
- HPGCC SD Card I/O . libfsystem unavailable. . f* calls unstable (HPGCC2) . f* calls stable (HPGCC3)
