flashjazzcat Posted October 30, 2017 Share Posted October 30, 2017 Yes: I'm still finalising the latest update so will dump the content of my Incognito ROM and send it to you for use in the external programmer. 1 Quote Link to comment Share on other sites More sharing options...

michomis Posted November 1, 2017 Share Posted November 1, 2017 (edited) I have access to other working incognito (from my other friend) with newest bios etc. If he dump his rom as an 512kB rom, can I use it to programm my flash SST39SF040-70-4I-NHE (already bought it) with an independent programmer kit (it will be Top3000) ? Or should this ROM be converted to bin format with other structure or so? I am newbie in this subject. edit: or maybe better idea is to dump direclty using programmer kit, but I am not sure, if I get his incognito soon enough. ROM from uflash can be easy sent by email.

flashjazzcat Posted November 2, 2017 Share Posted November 2, 2017 Yeah: You can program your ROM with a dump from his machine, but this doesn't guarantee to fix your in-place programming issue long-term, of course. To save you some trouble, I'll try to dump my Incognito's ROM today (I put the machine away the other day to make space for other work).

spudmanno5 Posted November 3, 2017 Author Share Posted November 3, 2017 (edited) Good news! I received the SIO2SD adapter earlier today, so i put that firmware.atr on it. Fired it up, and it worked first time, and updating went without a hitch! After getting used to some of the new layout and changing some of the settings I now have a fully working updated Incognito! I even put on the original Uflash.xex and (firmware update).rom files and fired it up to see if they were recognised (when they previously weren't), and this time they were found! Which means I should be future proofed for any further updates in the future! Huzzah! Many thanks for your help FJC!

flashjazzcat Posted November 3, 2017 Share Posted November 3, 2017 That's good to hear! I guess something about the old firmware was screwing things up. Sorry I didn't get a chance to send you the ROM, but happily you don't need it now. Watch out for a firmware update in the next week or so. 1 Quote Link to comment Share on other sites More sharing options...
Tempest Posted November 3, 2017 Share Posted November 3, 2017 Sort of off topic, but does anyone know the status of the Incognito 2? Quote Link to comment Share on other sites More sharing options...
michomis Posted November 3, 2017 Share Posted November 3, 2017 (edited) And I have tried 512kB rom, that I have found somewhere on AA (from around 2015), and it did not work so good even loader went wrong somehow. Anyway I got dump from my previous flash memory if anybody wants to check structure. orginal.bin Edited November 3, 2017 by michomis Quote Link to comment Share on other sites More sharing options...
michomis Posted November 3, 2017 Share Posted November 3, 2017 (edited) My friend sent me 512kB ROM file dumped directly from his Incognito, and it accually worked (under programmer of course)! Now I have latest version. Cannot still make flash under uflash though. I have tried 3 flash roms with no effect. Always same problem: Flash error! Retry? Flash memory is still unrecognisable at start of uflash. In attachment ROM, that I have right now, the one dumped by my friend.

flashjazzcat Posted November 3, 2017 Share Posted November 3, 2017 Flash error implies just what it says: even prior to the verification phase, a location written to the ROM does not read back as the expected value. It's a hardware issue. Quote Link to comment Share on other sites More sharing options...
michomis Posted November 4, 2017 Share Posted November 4, 2017 Ok, any idea what what can be broken, if flash seems to be fine? Checked by programmer kit. Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted November 4, 2017 Share Posted November 4, 2017 I guess bus instability of some kind. Latest versions of UFlash even work reliably on Rapidus hardware at 20MHz, so if you're getting flash errors on an otherwise known good flash chip, it's probably the old Phi2 timing issue. Ataris can be inexplicably fussy about these things. Last week I worked on an 800XL with minimal upgrades which kept booting straight to the memory test unless I removed the AtariMax 32-in-1 OS board. I tried a second 32-in-1 board and it exhibited the same issue, and both boards exhibited the same problems in other machines. It turned out that all of the A8s tested with the board didn't like the AMD flash ROM in the 32-in-1. I changed it for an Amic chip and everything worked perfectly. Was the AMD flash ROM in either board faulty? Not at all. Quote Link to comment Share on other sites More sharing options...
michomis Posted November 4, 2017 Share Posted November 4, 2017 Ok, but this Phi2 timing issue is related with incognito itself or an Atari? I could try to uflash it with another Atari 800, but no soon enough. Assuming flashes are correct, and Ataris are correct, could it be problem with another chip on incognito board (xilinx)? I mean, could it be manfulctioning somehow? Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted November 4, 2017 Share Posted November 4, 2017 Yes, it could also be an issue with the CPLD on the Incognito board. They were hand soldered and I've experienced problems in the past with older VBXE, U1MB, and Incognito boards. 1 Quote Link to comment Share on other sites More sharing options...
michomis Posted November 4, 2017 Share Posted November 4, 2017 Ok, thanks. In future, would it be possible, that you share on your web site whole 512kB ROM to be used by external flash device? With all updated bios? 3 Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted November 4, 2017 Share Posted November 4, 2017 Yes definitely: I'm aware that it's a notable omission. 2 Quote Link to comment Share on other sites More sharing options...
