Hi,

Quote:

But if once selected a *.HDF file name, I can not pick any other one. Master or Slave setting goes "disabled" and there is no way to get back to HDF file selection list. At some strange way I managed once to select another Master HDF file again, but Slave will auto-select the same file at once and can not be changed.

At first file select after PGM reset or power-up one have to press <enter/space> twice to reach file selection list for Master. First <enter/space> at Slave will automatically select "any" existing .HDF file (perhaps first in directory list) anc can not be changed.
As soon as Master HDF is selected, Slave will automatically take its name by attempt of selecting some Slave HDF file and can not be changed by hand.

Im sorry for reporting bugs again...

Boing4000 I'll investigate this

Anyway I think I should be the one apologizing here

I really appreciate all the testing hopefully I'll fix all bugs that way.

Maybe it´s not a bug but the hfd file which i have created loads very slow.
Opening a folder which contains nearly 30 files takes severals minutes(10 min.) on the workbench.
The hdf file has a size of 700Mb.
Is there a way to increase the loading speed ?

Dirk, HDF file emulation is slow because I can't use tables to speed up hdfile access like ARM controller does.
How ever there are few things you can do if you already didn’t and even for ARM controller is recommended to do same.
1.) Format your SD card with largest cluster possible, this way when random reading HD file PIC will need to search for new cluster less frequently and this will speed up disk access dramatically.
2.) You can use WinUAE to defragment your HD file this will also increase speed because Amiga will read data without too much seeking.

Hi,

I think I have fixed HD file selection/removal and also wrong default selection.
Here is attached latest pic HEX.

Thank you Quille for your additional work just before Christmas!

The new version works very fine, until now there is nothing but good news to report

OSD file list handling also feels faster then before, but could depend on used sd-card and present file amount.

It all seems to be working smoothly except I can not get it to save chipset defaults. Every time I turn it off I get

NORMAL
PAL
OCS

and I'd much rather have

TURBO
NTSC
ECS

Thanks for all the effort. I like it very much.

Thanks for reporting, I have found an error an fixed it.
Here is latest minimig pic hex, source is uploaded to google code ..

Merry Christmas,

Thank you very much and merry Christmas to you and yours. Sorry I'm so slow getting back but we had family in for the holidays and this is the first chance I've had to give it a test.

It all seem to be working, YAH! :mrgreen:

Thank you!

Hi Quille,

This is amazing work, thank you very much! I have tested it and it works well.

I think it should become the new standard firmware for the PIC users :-)

.

The only problem I have is that it is not able to run with the latest FPGA core from 241209..

I agree, this PIC release works very well, no problem so far

The adjustment to current YB091224 core is minor and should be no problem to implement.
I also could build a matching FPGA core to work with current PIC release, but the other way
would make more sense.
Perhaps also add a release time stamp to every GL PIC archive will help to find matching release version

Hi,

I have created new thread for pic firmware for new core YQ091224.
