Release v1.9 of the Agon firmware update utility
This is the official release of the Agon firmware update utility. It is suitable to be installed and run on any Agon hardware variant. It is fully compatible with either AgonPlatform MOS version 2.0.0 or later or Agon Quark MOS version 1.03 or later.
Use this version when flashing to MOS 3.0+ / VDP 2.14.0+
Release notes
The following issues were fixed in this release
- VDP 2.14.0 doesn't start up sending screen information back to MOS. The upgrade utility used this information between flashing vdp/mos to check if the VDP is ready to accept new data to output after a reset. This version explicitly sends the 'fetch screen dimensions' system VDU repeatedly until the VDP responds
- The assembly routine startVDPupdate did not save some registers that the main program calling function used, sometimes resulting in hangs using the 'flash all' command.
