Is the PIC firmware upgrade likely to work fine with yaqube's firmware? (I only have a 60khz TFT monitor here). In other words is it okay to upgrade the PIC firmware but continue with an older Minimig bin?


Well, if Yaqube has not altered the PIC code in any way to achieve the 60hz, then yes the PIC update will not affect it.

The PIC controls flashing of the FPGA, and MMC reading.

I've not used the Tiny PIC Bootloader before but I do have a serial connection established between my PC and Minimig (to use Amiga Explorer). Is this fairly straight-forward to use and is there any risk to the Minimig (I'm guessing it's similar to flashing a PC bios)?


Similar, sort of.  connect up Minimig to PC using nullmodem (and set the Jumpers).  Set the Tiny software to scan for the Minimig and quickly add power to Minimig.  The pic's listen window (for firmware updates) is about 1 second before it boots the main code.  If the flash fails (Loss of power etc), then when the power comes back up, just do it again, because the Actual boot code sits in a different location to the Firmware you are flashing.

@Dennis.  How is the multiple ADF function coming along (this would be a image swap life saver for multiple disk games).

New Pic18 firmware flashed okay.

SD card is currently in my Camera, so the Disk led flashes 6 times, so looks like it is working well so far.

I might try it tonight, at Maug.  (Melbourne Amiga User Group).
