HOME AUTOMATION Posted February 17 Share Posted February 17 But, in order to do an update of any kind, from an SD card. You must have a BOOTLOADER, on the AVR. After bricking mine, I was able to bring it back to life, by using a TinyAVR, programmer to reload the bootloader, from this file: package.hex 2 1 Quote Link to comment https://forums.atariage.com/topic/260917-the-finalgrom-99/page/32/#findComment-5412336 Share on other sites More sharing options...
fabrizio Posted February 17 Share Posted February 17 thank you very much, we assembled these FGs, the situation at the moment is this, AVR programmed with Atmel ICE and verified with a working FG. I don't understand if the problem could be with CPLD or with ATMEL. When I power the FG the LED flashes approximately 1 time per second, if I insert the SD with the CPLD programming file and do the reset, the LED flashes six times quickly, I have tried various SDs.. 2 Quote Link to comment https://forums.atariage.com/topic/260917-the-finalgrom-99/page/32/#findComment-5412341 Share on other sites More sharing options...
fabrizio Posted February 17 Share Posted February 17 thanks😀 the pld file works (80k) and I also checked on github, I continued to use this file always in github finalgrom99/vhdl/src/fg99-xsvf (1K) . I was probably wrong about something..🤬.

fabrizio Posted March 17 Share Posted March 17 hi, everyone, I have two fg99s with this problem, when I insert the SD card with the update.pld file the LED stays on, and never goes off. Has this happened to anyone? I tried replacing both the 328p and the Xilinix... 1 Quote Link to comment https://forums.atariage.com/topic/260917-the-finalgrom-99/page/32/#findComment-5431012 Share on other sites More sharing options...
HOME AUTOMATION Posted March 17 Share Posted March 17 Hmm, I believe that both chips are made by Xilinx. That's how mine behaved after a failed update, where I loaded a file that was too long. If you are replacing the 328p, I think you'll need to install the BOOTLOADER, by using a programmer. 2 Quote Link to comment https://forums.atariage.com/topic/260917-the-finalgrom-99/page/32/#findComment-5431159 Share on other sites More sharing options...
fabrizio Posted March 18 Share Posted March 18 They are new constructions, I have built 5 of them, two without problems, three have this defect, I was wondering if anyone assembling these PCBs has had a similar problem.

ralphb Posted March 18 Author Share Posted March 18 Based on your description, I probably had an error similar to yours at some point when I built my batches of FinalGROM. If the LED doesn't blink, it's not a "regular" error, like file not found. The error codes returned by the JTAG library are also translated to LED signals. I assume the working and non-working boards have the same AVR software? If so, I would check if you have bad solder somewhere so that some signals are not going through. Also, did you set the AVR fuses correctly? How long did you wait for completion?

Se il LED non lampeggia, non si tratta di un errore "normale", come file non trovato. Anche i codici di errore restituiti dalla libreria JTAG vengono tradotti in segnali LED. Presumo che le schede funzionanti e non funzionanti abbiano lo stesso software AVR? Se è così, controllerei se hai una saldatura difettosa da qualche parte in modo che alcuni segnali non vengano trasmessi. Inoltre, hai impostato correttamente i fusibili dell'AVR? Quanto tempo hai aspettato per il completamento? the FW is the same for all and the lock bits are the same (checked directly with atmel-ice), I attach both the TDO and the TCK seem blocked by something. I assume that the update file is read well since the LED lights up steadily, are the CD0-CD7 bits affected when programming the cpld?

fabrizio Posted April 16 Share Posted April 16 Finally the cplds arrived, replaced with the new batch and, finally it works... In the previous batch out of 10 xilinx only three worked.... 9 Quote Link to comment https://forums.atariage.com/topic/260917-the-finalgrom-99/page/32/#findComment-5449898 Share on other sites More sharing options...

Douglas Hi everyone, they brought me an FG99 with the RAM (as6c8008-55), apparently it seemed to work until we tried the (TI extended basic), the FG99 blocked, I replaced the RAM with (cy62158) no problem. Now I don't have an AS6c8008 to do other tests, but I would like someone who has the fg99 with this ram to do some tests with the TI extende basic.

I note they require different .AVR and .PLD files - available here: finalgrom99/updates at master · endlos99/finalgrom99 First, confirm the console type: TI-99/4A FAQ: Console Version Differences - arcadeshopper.com If it is QI, you can update your FinalGROM by downloading the firmware_qi.pld and copying to your SDCard as UPDATE.PLD, and download version_qi.avr and copy to your SDCard as UPDATE.AVR and power it on. I think you also need to remove those files from the SDCard when it's done to prevent it from trying again at next boot. If it's not QI. I guess there'a a chance Brewing Academy didn't program the CPLD, but that does seem unlikely. 1 Quote Link to comment https://forums.atariage.com/topic/260917-the-finalgrom-99/page/32/#findComment-5556202 Share on other sites More sharing options...

From the FinalGROM repository link (finalgrom99/updates at master · endlos99/finalgrom99 ) download firmware.pld. Copy it to the root of your SDCard as UPDATE.PLD, plug it in, turn it on and it should sit there and update (almost solid LED for 10 seconds or so). Once it's done updating, just check the SDCard and see if that file is still there. If it is, delete it. 1 Quote Link to comment https://forums.atariage.com/topic/260917-the-finalgrom-99/page/32/#findComment-5556702 Share on other sites More sharing options...
