[1036431.859] format yes

it appeared hung here so i rebooted.

only then did mios studio say:

[1036683.414] Formatting SDCARD…

[1036683.414] [GET_SECTOR_COUNT] Count is 7741440

[1036683.414] [GET_BLOCK_SIZE] Block Size is 0

[1036683.414] [disk_write] error while writing to sector 13973

[1036683.414] Disk Function Error

[1036683.415] SD Card disconnected!

[1036683.417] [disk_read] error while reading sector 0

[1036683.417] Failed to open directory / - error status: 1

so it was formatting? but REALLY slowly?

how long should it take?

:ahappy:

progress!

It should be pretty quick (a few seconds)…

This looks like another CSD issue:

[1036683.414] [GET_BLOCK_SIZE] Block Size is 0

This should be (16<<csd.DeviceSizeMul) although for some reason your DeviceSizeMul is 240 and 16<<240 will wrap quite a few times. I would expect DeviceSizeMul to be between 7 and 9 !!!

Leave it with me for a while and I will see what I can do :slight_smile:

Cheers

Oops, double post (it looked like it had hung!)

44

OK try it now.

I have tried another option which uses: 16 << (csd.DeviceSizeMul>>4) which should be a more reasonable number.

Try the latest svn!

Cheers

somethings not right, but it’s close (very close even).

is it usable now? :ermm:

…this took ~3hrs!

That may be my fault… I inadvertantly left debugging on when I committed my last change. That logs every read and write to MIOS Studio which will “massively” slow the operation down :slight_smile:

It should be quite a bit quicker now.
