FAT32 for T5

[dmitrygr]

This should(but not guaranteed since i do not have a T5 to test on) work for T5 users
install to RAM by copying from from card, not by hotsync
tell me how it goes

[lclark2074]

just cpoy it in internal/palm?

[dmitrygr]

to ram yes

[palmgeek5394]

I'll try it here in a minute or two. I have two different backups (all recent) from two different apps in two different places. So I'm not too worried about reset loops and the like. ;)

[palmgeek5394]

Didn't work. Hard resetting now.

[dmitrygr]

what symptoms of not working?

what symptoms of not working?


After copy to ram and softreset the T5 hangs on the "palm powered" screen with a blinking bar on the top of the screen.

Warmreset with button up don't work. Only hardreset works.

If you want another try, i am here.

[dmitrygr]

hm...this would be infinitely easier if i had a t5 :(

[dmitrygr]

OK...try this please
install this app to ram and run it once.
then run again, and it will confirm the driver is installed.
then insert a FAT32 card in.

this worked on my E2 (which would not accept normal driver installation)

[palmgeek5394]

IT WORKS! :D Reading a FAT32 card right now, seems to run faster (probably is. Dmitry's probably put in multi-block writes. And maybe just a larger cluster size. [because it's FAT32] :rolleyes: ) Works well. Even soft resets well. :cool: Thanks! :D

[dmitrygr]

can you please try this: http://www.palmpowerups.com/priv/zF32.prc

soft reset
and run it


also as a note: fat32 is not enabled after soft reset - you need to run the app again to enable it

[robitaille88]

If there was a pop-up showing it's scanning, it wouldn't be too bad. I generally only use 1 SD card anyway. Though I supposed it's rescan on device reset, eh? What's the advantage of card scanning anyway? Faster access?

[dmitrygr]

can someone please test the above new posted driver?

[Another Michael]

can someone please test the above new posted driver?

The driver recognise the 4GB SD card from my TX. (formated with FAT32 and 16kB Blocks with my PC.)

---

It don't survive a softreset. I have to manually start the driver after a softreset to activate him again. (Softreset, start driver, remove and insert 4GB card to recognise the card again.)

---

Then i want to start a program from the SD-card, right after softreset and activating the driver. Here "UniCMD" and "Bejeweled2". But the T5 says "can't start app because of not enough memory".

---

Test with NVBackup: Backups starts but the a message says: "Cannot locate hidden volume".

Write a full set of files to the card that can't be deleted by NVBackup or a PC with a cardreader.

---

If i go the the standard palm launcher an activate "Info" or "Delete" then i've got a serious error (with resuts in a softreset)

"Emul68KMain.c, Line:108, devide by zero at address 206F24C0"

---

Next test: Open a jpg picture located on the card with the palm app named "files":

serious error (with resuts in a softreset)

"StringMGR.c,Line:68,NULL string passed"

---

Open and play a MP4 Video from card with tcpmp:

Works. No stutter. Seems to read fast.

---

Test: Copy app to card with palm launcher: Works.

(But if i want to start it from card it says: Not enough memory)

---

Test with cardspeed

Wrt32bit: 266 bytes/sec
Wrt8kB: 391259 bytes/sec
Read8kB: 1379705 bytes/sec

Test results: "card speed is Excellent / Use any record setting"

---

Cardinfo from palm reports a card size of 1711.4MB (from the 4GB card)

Format with Cardinfo seems to work. (But all the problems mentioned above don't vanish.)

---

[dmitrygr]

hm..ok try this then: http://www.palmpowerups.com/priv/zF33.prc

[Another Michael]

hm..ok try this then: http://www.palmpowerups.com/priv/zF33.prc

Survive softreset:

Depends on format characteristics.

----

Start apps from card:

Works

---

Show pic from card with "files"

Dont work (serious error as above)

But: Show pic with RescoView works.

---

Info and Delete from palm launcher:

Works, no more crashes.

---

NVBackup:

Do a new backup: Works.

Write Backup to T5: Works.

[dmitrygr]

ok good. it all works :)

[Another Michael]

ok good. it all works :)

Mostly.

If i format the 4GB sd card with the T5 it recognise the card also after a softreset. (without starting the FAT32 driver manually after softreset.)

But if i use my PC formatted 4GB card from my TX, the T5 ask if want to format it after softreset. (it will recognise it only after starting the driver manually.)

[dmitrygr]

of course...t5 formats 4gb as fat16, which is technically invalid
pc formats it as fat32, and without driver palm cannot read it

you need to re-enable the driver

[lclark2074]

how do you put in ram step by step

[dmitrygr]

with this driver...any way u want
just install it ot device and run it once

[lclark2074]

i instald the zf33 driver and it sill dos not recenise sdhc card witch is not formated now.

[lclark2074]

shud i reformat with the computer to fat32?

[robitaille88]

shud i reformat with the computer to fat32?
Probably the best idea. I'm not sure if Dmitry created a FAT32 formatting routine for the T5

[lclark2074]

yes he did right driver for T5

[dmitrygr]

i instald the zf33 driver and it sill dos not recenise sdhc card witch is not formated now.


why would it? unless your device can read sdhc, an sdhc card will not read!

further more this is not my driver...just a much more advanced patch on palm's

[tosbsas]

any hope to get this for t3 too?

Ruben

[dmitrygr]

the last posted link should work on t3 as well

[luismedina]

So, if I install zF33 in my T5, it can read SD up to 4 GB instead 2 GB default?

[tosbsas]

the last posted link should work on t3 as well
anyone tried this??

I already got one fat32 from you -this one is better??

Ruben

The earlier one doesn't work on a T5 IIRC. This one does, but is designed not to persist across soft resets (since it's still a test version). This driver adds support for FAT32-formatted filesystems, and should be able to handle large filesystems (up to 1.5TB or so IIRC) as long as the rest of the driver chain supports the size as well (which it doesn't). As long as everything else supports 4GB, this driver should too.

[cstamper]

I'm gonna try it on my T5 soon as the backup is done...

So this looks like just the prc from the TX, patched right? I've tried it 'un-patched' and it didn't work...

Thanks dmitry!

[cstamper]

Ok, it works w/ no obvious errors. However it does *not* persist after reset. And that works for me, because I don't want it to; I just want to have FAT32 available if needed.

Thanks!

(I used the last version posted, zF33.prc)

[lichan]

When I use the zF33 driver on my E2, it works with my 1GB SD card which no previous FAT32 drivers would but does not sense a 2GB SD card on installation. I assume it's formatted as FAT16 but shouldn't the new driver be able to see it?

[dmitrygr]

will someone please answer this, because if i do it, i will just explode from having to do this 1000000000000000000000000000000 billion times in the past

[tosbsas]

@lichan
As far as I know, thats a fat32 only driver so of course it will not see a 16bit card, just format it and you'll see

Ruben

[dmitrygr]

false. this driver will read fat12, fat16, and fat32

[lichan]

The 1GB slot driver limitation on the E2 must be the problem. A 1GB card formatted in FAT32 (via Linux or Windows 98) would then work on an E2 with the zF33 FAT32 driver.

[dmitrygr]

that is correct. the SDHC driver supports cards over 1GB easily...

[palmgeek5394]

false. this driver will read fat12, fat16, and fat32
I've noticed that. Is that how you get around the T5's RAM and internal drive being FAT16? ;)

[dmitrygr]

no. i just leave the old driver loaded, but also allow this one to load, so fat12 and 16 are handled by old driver, and if ti fails to mount something(like a fat32 FS), the new driver tries it.

[tosbsas]

sounds cool

Ruben

[cstamper]

Is it supposed to persist across resets? (Doesn't for me)

Since its apparently using the original driver for fat16, I wouldn't mind using it all the time.

I could make a quick app to fix it. Anyone interested or am I the only one w/ this problem?

As it's been stated multiple times, the T5 FAT32 driver is not meant to persist through soft reset. I believe that the files he linked here are for testing purposes.

[dmitrygr]

that is on purpose...for now
