Possible problem with ver 1.0.6 #1

Closed jgilcas closed 9 months ago

jgilcas commented 4 years ago

Hi.

I think there is a problem in version 1.0.6. When writing to the SD card the file system is corrupted. I have tried with previous version (1.0.4) and is working ok.

Thank you.

Hi. I can confirm that I am experiencing the same issues exposed by @jgilcas. Using the 1.06 version I get eventual data corruption on the SD, becoming this non usable.

I've tried several SD brands and sizes, and altough it's somehow a random pattern, they do get corrupted after some SDMapper usage.

Thanks!

I confirm too. Just flashed new beta 2 kernel version and as i write to SD filesystem is corrupted.

I tried latest commit with Nextor alpha2 (commit 9cca901cadc1501308d6b337f174472c8b41a7b6)

Flashed its SDMAPPER.ROM and i discovered that it still corrupts the filesystem!

It seems that bug occurred not with Nextor beta2 support but before!

Update: i noticed also that this bug also prevents SD detection from _FDISK (basic)

I found a possible problem related to this issue.

In driver.asm variable CODE_ADD value is 0F84Ch but in Nextor version beta 2 this variable has changed.

Its new value is F1D0h. (Breaking Change) Check here https://github.com/Konamiman/Nextor/releases

Hello, Fabio. Same problem here. SD Card gets corrupted after write anything on it after the update. Any tip to fix it? Enfrentando o mesmo problema aqui. SD card corrompido ao gravar algo nele após a atualização. Alguma dica para reparar?

And 1.04 version was removed from tags, considering its the only stable working version

I found a way to return to version 1.0.4 and fix everything! Using the SDMAPPER_patch_ciel2+.ROM file (https://github.com/fbelavenuto/msxsdmapper/tree/master/Driver) to rewrite the EPROM. Now everything is back to normal, that is, no more corrupted SD cards!

Eu consegui uma maneira de retornar para a versão 1.0.4 e consertar tudo! Utilizando o arquivo SDMAPPER_patch_ciel2+.ROM (https://github.com/fbelavenuto/msxsdmapper/tree/master/Driver) para reescrever a EPROM. Agora tudo voltou ao normal, ou seja, sem cartões SD corrompidos!

Hi Guys, please test this ROM:

Nope... It crashed and I lost everything on the SD Card again even with this new version. This time the data was still listed, but corrupted. And you can't create folders nor files.

Bug fixed, please test with latest release (SDMAPPER.ROM was updated)

Emily82 commented 9 months ago

I just tested the latest sdmapper.rom with the latest smupd.com, flashed it but the problem isnt fixed. I created a text file with ted.com and it gets corrupted, it was renamed with garbage characters.

Now i flashed it back to old 1.04 and it works well.

fbelavenuto commented 9 months ago

Fixed, get the latest version on release page (1.0.7)

Emily82 commented 9 months ago

Yea it works now! I tested it and it seems also faster copying files from my gotek to sd. Before with 1.04 version it was very slow.
