Sansa c200v1: recovery mode

[BlindWanderer]

So the sansa c200 has a recovery partition. I'm considering repartitioning my sansa c200 and I'm not keen on bricking it. Does the recovery partition need to be the second partition or the last partition?

There is no recovery partition on the c200v1.  There is the firmware, which is not accessible over USB, and a recovery mode, which is a RAM disk. 

I'm not sure about repartitioning.  I suppose at worst you could also use the recovery mode to format the device.  Why do you want to do this?

The firmware is accessible over USB. That's what the second partition is. You *need* that second partition to boot.

You're right.  I thought you had to be in recovery mode, but looking again, it is exposed over USB.

Ok that makes a lot of sense and now I'm able to make better sense of main-pp.c, for RB Bootloader it needs to be the second partition.

Is it the i2c bin that bootstraps the bootloader firmware? If so does it read the partition table or is it using some hard coded sector number?
