seems the new os is buggy :( it freezes at the init ... screen
Might also be a damaged download I have tried downloading it a few times.
here are the checksums for the file in question.
CRC-32: 354BFC5E
SHA-256: 5195E5A6FBC7145385BDA50E5BB0AA4F95AA8C22202B4AE542070CE53001060A

Good job on the A/B swap. 

Game Genie codes still don't work, however.

The loading sequence is as follows :

disk init...
fat init...
OS loading...
[clear screen]
init...
[clear screen]
init...
OK
[Menu]

For those who tried to load this os file as I did - it should not be loaded manualy, put gbos.gb into EDGB folder of sd card - it will load itself on boot.

sounds like you have the same issue as I do on the GBC or GBA sp it just loads the last rom.

Mine also bootloops to the last loaded ROM when used in my GBA. Removing the GBOS.GB file lets me get back to the menus again and pick a different game.

Tried that. With no manipulation with sd card EDGB with OSv2 in gameboy classic works (blinks init twice, than boots os v2), in gameboy color blinks init twice (like striggles to load os v2), resets to last game. Absolutely reproducible. Maybe GBC current or voltage is low to drive edgb osv2 boot? It's only 2 batteries, after all.

Tried that, with sdformatter. Didn't help. When update file is removed boots fine on GBC. Updated os resets.
Works perfectly on GB classic.

US Super Gameboy: Works.
JP Super Gameboy 2: Works.
US Gameboy Advance (non-SP): Reboots into last loaded game.

Has anyone out there gotten v2 working on a non-SP GBA or the Gamecube Gameboy Player?

I found a reason for my problem - it's sd card. EDGB is picky aboud sd cards, but OSv2 is even more demanding.
I started swapping sd cards, and absolutely unbranded 2G microsd card from aliexpress worked! silicon power 8g microsd(hc) booted OSv2 only on classic brick, verbatim 8g microsd(hc) made EDGB to show hex error on power on.

So, now I got OSv2 tested working on: Classic DMG-01, Color CGB-001, Advance AGB-001, Advance SP AGS-101.
Format tool used: windows format to FAT32, sector size 4k.
Card used: noname 2gb microsd card (only one that worked for v2 on every device I could test)

SP and Verbatim are class 4, unbranded card is, well, 2gb in size. No more markings on it. Under seek time you probably mean access time - I have to run IOMeter to test, will do it later - repeatable test setup consumes some time.

32GB SD card need be Class 10 anything less than 10, will fail to load OS
16GB SD card need be Class 8 anything less than 8, will fail to load OS
8GB SD card need be Class 6 anything less than 6, will fail to load OS
4GB SD card need be Class 4 anything less than 4, will fail to load OS
2GB SD card need be Class 2 anything less than 2, will fail to load OS
1GB SD card has NO class ranking

Access Time need be 0.81ms or lower, anything more than 0.93ms, will fail to load OS
(according to sd2snes' sd card page)

Error most cause by sd card is:
FAT32 system file is corrupt by bad blocks or fragment files

This also complies with any other Everdrives

This is a good answer, but it still eludes me why same everdrive gb with same sd card boots os v2 on gameboy classic, and refuses to do so on gameboy color and advance.

Perhaps because Gameboy classic has lower cpu clock.

I've got a few 1Gb, 2Gb, 8Gb and one 16Gb - could only get v2 to boot on a brick GB, kept reseting on the GBC. The only cards that worked OK on the brick were an unbranded no markings 2Gb and a class 10 16Gb. None of the other cards I have would boot into v2 on either.
Too bad it won't work on the GBC without a randomly lucky card :/

your sd card does not meets standard of speed of that size

Because OS v1 is built-in on EDGB board and OS v2 is on SD card
If sd card is too slow, EDGB will fail to load OS v2

I tried a sandisk ultra 32 GB micro sdhc (class 10) with my Game Boy Colour and experienced the issue where it would just skip the OS menu and boot the last ROM that was played.  I used this same card in my Super Game Boy for the SNES and as able to access the OS directory without issue. Very strange.

I then tried a Kingston 8 GB micro sdhc (class 4) and it also works perfectly in my Game Boy Colour!

I'm happy it works now but curious as to why the class 4 worked in my Game Boy Colour but not the "faster" class 10?  Maybe the storage size difference between of the 2 cards is part of the reason?

I put the new OS update in my EDGB folder, turn it on, and it says

init...
fat something
os loading...

then when in the menu, the button swap is still the old way, which means the new os update is not loading. I have a samsung 2GB card.

Did you press Select to get the ED main menu and change the swap key to Yes?
Title: Re: EverDrive-GB OS v2
Post by: VectrexRoli on September 19, 2015, 05:42 PM
I came also to the same result that was already mentioned before: The new OS2 seems to have an influence on the compatibility of the used Micro SD card. An old no-name 2GB and an older 8GB Kingston did work without any issues, my SanDisk Ultra 32GB did not work anymore on OS version 2.
I also still had the latest SanDisk Extreme Plus 32 GB model from my EZ-Flash IV review lying around here and same issue there - BTW, KRIKzz I still hope that a new Everdrive GBA will come out as the PC client you need also for the new EZ-Flash IV is total crap, especially when trying to get it running on Windows 10...  ;)
Anyway, that behavior is independent from the Gameboy model used. It is not a big thing as long as you still have access to older or smaller Micro SD cards and I like the fact that I can swap A and B now.  ;D

No but if it's a timing issue with only the gbc it should be fixable on the software side, but maybe it would have to be fixed in the firmware, and that would of course be a different matter I guess.

Hi

I have the same problem with OS2. As soon as I put the new OS on the memory card, the everdrive reboots and plays last game. I have tried this on 2 SD Cards, although both were the same model...

This was tested on GBA SP and a gameboy Color

Any ideas anyone?

This is not true. Not just there are a lot of reports that "compatible" cards don't work, but even cards that work do this on per device basis (work on some gameboys, fail on other)

Let me put it this way - changing sd card helps, but just putting sd or sdhc card won't work. Old 2G or less in size cards tend to work (with os V2 on all gameboys, classic, color or advance), but this recommendation is not bulletproof. It may work with osv2, and it may not.
Title: Re: EverDrive-GB OS v2
Post by: saturnu on September 22, 2015, 07:02 PM
beside that, there are many sdcard fakes on the market, even on amazon or local stores. ^^

it's not always easy to tell if the sdcards are genuine ones or not.
so if your card is on an incompatible list, it's still worth a try. :>

of course my list is not bulletproof
you should ask to SanDisk why their fastest card have bad "Access Time"

2GB SD card has Spec version 1.01

like other users said

not all sd card(s) made with the same parts
some will fail, most will work

gbc and gba slot(s) access time and power supply are not made equal
will cause different results, most will work for others, some will fail

beside that, there are many sdcard fakes on the market, even on amazon or local stores. ^^

it's not always easy to tell if the sdcards are genuine ones or not.
so if your card is on an incompatible list, it's still worth a try. :>
SD card is Spec version 3.01 or higher are not backward compatible

Everdrive compatible with SD card is Spec version 2.00 or older

Just adding my experience...

EDGB in a Super Gameboy 2 runs fine.  It loads the file menu up and u can pick a game, upon reset it loads the same game like normal unless you completely turn off the SNES.

EDGB in GBA SP simply loads the last game up...no file menu at all

EDGB in Gamecube GB player loads the last game up...no file menu at all

for the time being i just deleted the new os and all my gameboy playing devices work flawlessly with the everdrive gb

Still wrong as like I said in my last post, my 8 GB class 4 card works fine both on GBC and GBA SP. Doesn't mean at all that this is the case for all class 4 cards of course, but it proves your blanket statement about needing at least class 6 for 8 GB wrong.

The most important statement is
Quote
Access Time needs be 0.81ms or lower, anything more than 0.93ms, will fail to load OS
SD card class and markings are not important what matters is the raw performance of the card overtime. What matters is luck.

On a minor note, I realized the "system type" display is gone in v2 now.

This is indeed the best conclusion of all those SD related issues.

i wanted to say, that it's possible that with some fake cards, someone could just owns a spec 2.00 sdcard instead of a 3.01 one.

here is 64GB SDHC on the picture
it's somehow out of specs for a SDHC (<=32GB) and i'm pretty sure that many SDXC cards are just SDHC ones and that the controller says something about 64GB but the is is only 16GB in size.

Have tried 4 cards now, all with the same problem.

I will try the new V3 in a couple of hours on the same 4 cards and let you know Krikzz.

SUCCESS!

Krikzz, I have tried the version 3 on..

SanDisk Ultra 8GB class 10

&

Sandisk 8GB Class 4 (not sure if genuine or not)

Both failed before, but both have loaded up the new OS - and I can swop the keys!

Good job!
