It should be ok in Altirra - I loaded it up there before flashing to my 1200xl. Worked great on both.

Yep: I guarantee it, as I said. :) The firmware is flashed in Altirra before it's even flashed on real hardware.

OK all better now thanks for the tip about a cartridge being attached.  I have been trying to get the Koala painter cartridge installed for the last couple days and it was still attached when I tried to FLASH..

It has. It was accomplished via a PMG underlay and I needed the RAM for more info in the slot properties dialog.

Do you have an Incognito build that needs testing?

 

PM sent. Anyone else interested, please let me know. Nothing bad came back from the U1MB testers, so release is imminent (finally!). :)

Incognito loader is still registering as version 1.28

 

EDIT:  Re flashing the loader fixed it and thank you...

Hey Jon -

 

Any idea when you'll call these "done" and make them available? I'm looking to update my 1088XEL this weekend if you've got a build ready. :) I'll also update my Ugly Duckling 1200XL while I'm at it.

I'll PM you the latest RC builds later on. I've somehow been detailing the 1088XEL's loader for the past week (the dual drive aspect threw up some interesting usability issues), but I'm pretty happy with what I have right across the board now.

Time for an update, I think. :) The constant postponements with regard to releasing the firmware turned out to be blessings, since a nasty bug concerning AtariMax carts was brought to my attention and fixed a month or so back, and this evening I think I've fixed SD/CF adapter operation, which was hitherto extremely flaky in the loader. Turns out the SD/CF adapter wasn't always sending DRQ low following a transfer, and on top of this it flipped out when a new command was issued before DRQ deasserted. No such issues exist with 'proper' CF cards, and the fix for SD/CF adapters is cheap (spurious data register reads issued until DRQ deasserts prior to issuing the next IDE command) and free from side-effects. I know quite a few people purchased the SD/CF adapters that Lotharek started selling and that's why I spent three evenings looking into the issue until I figured out what the problem was.

 

I've issued the update to a couple of people who reported problems with these adapters and if their feedback is good, I'll release the firmware immediately afterwards.

Sweet!!!

 

Not always I say this but... THANKS for such *amazing work* and continuous effort to distill pure quality throughout these years...

 

And, of course, quality DOES take time! ;-)

Appreciated. One of the testers got back to me already and said the update completely solved all his problems, so it looks good. ;)

Hi Jon - any update on release versions (especially for the 1088XEL)?

Yep: basically as soon as possible. The partition editor is getting an update as well, but I won't hold up firmware release for that. ;)

For those patiently waiting for the firmware update: I now have the slight issue of my Incognito board having developed a fault with extended RAM, resulting in D5 of PORTB being ignored and all extended RAM models being half the size they are supposed to be. This is a confirmed hardware fault (even the original Incognito firmware displays the same behaviour), and has not been fixed by replacing all jumper wires and ribbon cables. Fortunately the firmware update is complete anyway, and I'll stop trying to troubleshoot the issue and get on with releasing everything. It's fairly typical that my own hardware ends up wearing out while I develop software updates, of course. :) It's only unfortunate that I wasted an entire evening suspecting a bug in UFLASH when in fact it was a hardware error causing the board to be bricked every time I tried to flash a 320K SDX build to the ROM.

Success: the CPLD must have suffered bit-rot. :) I finally dug out the JTAG cable and reprogrammed the Xilinx chip and 64 banks are reported again.

I've seen problems crop up with the CPLD code on U1MB boards a couple of times in the past (even when no voltage spikes were involved) so I figured this was worth a shot. I had an U1MB board sent in last year which caused a system lock-up every time UFLASH was started, and was completely fixed by reprogramming the CPLD.

Anyway: back to business. ;)

don't sweat it, this sort of thing has cropped up on a number of people with u1mb's, I just wish there was a solution to why it happens and how to prevent it.

glad you figured it out before it drove you crazy!

Really? I don't remember reading of CPLD bit-rot in any unit other than the two I mentioned. It seemed the issue was extremely rare.

nope I've done it for a few people....take the laptop and the cord for a quick trip.... and in a few minutes they were back in business... it's not just you. The universe sometimes conspires against all of us.  I do notice a slight pattern though.... those who move their machines a lot or tinker are the ones that need it. Others  that just leave it plugged in and on the desk with everything hooked up not so much. Now the real pain in the *ss is the sio2sd atmegas all the time.... people who own those I suggest get their own setup on standby for when they flake out. :)  I've got two sio2sd's sitting here right now (seems like always 1 or 2)... sigh, I've not even bothered yet. Now that you mention it, I should wire up new sio cables for them program them and pass them off to the kids....

 

I really need to show a few more people how easy this stuff is so when I kick others can make house-calls and the off retro clinic, before I forget which end of the iron to hold or push up daisies... it's already evident my wording and editing is history. Takes half an hour to type a rambling mess out. This muddled mess took more than ten minutes and it's full of issues...   good days and bad days....

Sorry to hear that. But I've also started noticing problems with using the shift key when typing. It seems that my brain doesn't know how to sustain a held down shift key long enough for it to register with another key. After I write a sentence or two and re-read it, I see lots of things that were supposed to be shifted but are not (just had to go back and change two instances of 'i' to 'I' in this sentence). It's not a physical thing, so much as a mental issue. But if that's as bad as it gets I'll be perfectly happy. Just a little 'bit rot' of the brain is all  ;) .

Exact same issue this evening when flashing another 320K SDX ROM to the Incognito: bricked the board, and discovered that the last 64K of the SDX image got flashed to the bottom of the 320K region.

 

Presumably the Xilinx is shot and needs replacing. This is definitely not aiding the push to get everything prepared for release.

 

EDIT: Won't reprogram using Impact, so the Incognito is U/S until I get time to repair it.

 

EDIT: Angrily reflowed the CPLD and it appears fixed... This whole process now resembles death by a thousand cuts. :)
