TF1260 New Firmware Alpha Released!

[apolkosnik]

Mr. Terriblefire.,

First and foremost, mad props on this new release!
My TF1260 that I got from Alen has been rock solid stable on Rev6 at 94. Thank you both for making this very affordable option available to general public.

I didn't have lots of time to do a more thorough testing, but my go-to demo:,Andromeda's Nexus7, runs much better on this than the previous firmwares.

Regarding issues, maybe a github repo with issue template for reporting would save some time if the card builders could help and triage some of them.

Thanks again and happy holidays!

Did you try the fw i sent in PM? it has different startup timings.

I did, same behaviour unfortunately. (couldn't PM back)

Same for me.

Before getting too much deeper into things try the things Gadget suggested with PSU connectors.

I'm also seeing that on the friendly Polish website there is one guy having issues with CPUs at 100Mhz. Claims his CPUs will do 100Mhz because they work on Warp. Well you need to boost your CPU core voltage to get a stable overclock on some CPUs. I am told warp does this. There is plenty of things out there about how to calculate your CPU boost voltage for a stable overclock. Its not something TFs do. They all use some form of 3.3v regulator that is not a TF designed part. So you are on your own if you CPU is not stable at 100mhz by itself.

That said i think the BUSCPLD is getting too hot and this may be contributing. I would invite people to freeze spray this and see if it helps at all. It might help me with deveopment.

Unfortunately the individual having issues is just being macho about his CPU stock and is demonstrating that he really doesn't know very much about either electronics, amigas, 060 cpus or just how to accept help.

Just updated mine via RPi.
2B + timing fixes
Custom ROM with EHIDE (not tested on this firmware)
Standard case with heatsinked CPLDs and fan blowing over TF1260
Recapped 4.5amp PSU

Great work in the elf factory creating this for crimble 94 and 100Mhz working here on full Rev6. 50-67Mhz ok. Not sure if it helps or was noticed, but 82.5 does seem to actually just be 50Mhz (I know +67 - 94Mhz is currently funky).

Next will be to pop the case and get the IDE moved over to the TF1260. Cheers

I'm using a Meanwell modded PSU and a Heavy standard PSU. My connections are always clean and well maintained, so I know it's not that.
It may well be a power issue though, I wouldn't rule it out. I may have to dig out another PSU and see if there is any change.

I do however think that those pins you mentioned earlier are shorted, I will have a look under my scope tomorrow and report back.

Well well well.. Sometimes im right

Well well well.. Sometimes im right

The fact you brought that pin into play made it a prime candidate
I went to test it being shorted under the scope and it was loose.

Easy to miss when it wasnt used and an easy fix.

Thanks for the help
