Hello,
I'm sure this is really an obvious question for those in the know, but I am really unsure on this one, and being updating firmware and it's a risky thing in itself (especially upgrading from an early firmware, with U-Boot needing to be updated). I have done my best to search and search, going through this forum, going through documentation available, tutorials and nowhere have I found a clear answer on whether I can upgrade from 1.2 to 2.1.1 or if I have to go through different updates.
On some reports, it is said that "all updates include everything in previous updates, therefore just go to the latest" but on others, I've read that "if you jump from an early firmware to 2.0.0 it can cause problems, you need to go to 1.4 first" and that "you cannot go straight to 2.1.1 without going to 2.00 first". Trying to find a definitive answer on the wiki, the documentation or the FAQs has proved inconclusive, therefore I'll hope you'll accept this question - I did my best to research. If it was anything other than a dangerous firmware upgrade, I'd just give it a try, but I really don't want a bricked gp2x at the moment.
My question is (finally, and if you haven't already guessed
), I would like to upgrade from my early 1.2 firmware to the 2.11 firmware (not too keen on 3) but I don't know if this is possible. Do I need to go first to 1.4, then to 2.0 then to 2.1.1, or first to 2.0 then to 2.1.1 or what should I do?
My second question is, how long does a firmware upgrade take? I've heard reports of people doing it in a few minutes, to people having to wait over half an hour for it to complete, but no definite answer, so I'd appreciate some sort of idea, so I can know if something has gone wrong.
Furthermore, if the firmware upgrade goes bad (knowing my luck it will), is there any way to use JTAG to unbrick it, if it's U-BOOT that gets corrupted? I've been out of the gp2x scene for quite a while, and when I was last around, JTAG was considered a possibility but it wasn't really possible, due to missing hardware or software support, if I recall correctly. I am quite happy to purchase a BOB (I would like one anyway), would there be any to fix a bad firmware update using JTAG now? Are there any guides on doing this? There are mention of such guides going to be written, and that JTAG can work, but again my searches have turned up inconclusive. I've read that my retailer (gp2x.co.uk) don't fix bad firmware upgrades, so I'd like to know this before I end up with a brick
Thankyou in advance
