Yes I can run code on the target.. a nice way to develop :)

This is what I get when starting:

Hello World!

I'm not convinced that the power-off code is working as intended.

As I understand it, the PCF50606 automatically powers the unit off when a) the power key has been pressed for >1sec and b) its ONKEY1S interrupt has gone unacknowledged for 8 seconds. I think that is the behaviour currently being seen (hence the delay).

Yeeze: I got your PM, thanks for the screen caps. I'm currently digesting the information in there, should be useful. Now I need sleep :P

Hi all,

I just submitted a patch to enable ECC in the NAND driver. The error rate on my D2 seems to be fairly low, but I figured we'd need this eventually so here it is.

FS#8669

You won't actually notice anything different in the bootloader unless you've written code to test file reading.

shotofadds:
Much appreciated, that was on the to-do list.

I'm currently in the process of re-working the NAND driver to make use of the write cache (block type 0x15) segments. When that is done we should have a reliable read-only filesystem and the 'real' work can begin to boot the main Rockbox image. 8-)

/me kicks himself to update the TelechipsNAND wiki page...

There's not much progress to report this week I'm afraid (I've been spending too long killing off my brain cells with beer ;D) but I thought those following this thread might be interested in a quick photo:



This is what I failed to show at 'DevConPub' this week: it shows the D2 booting as far as the Rockbox logo and version number, and then freezing soon afterwards.  But it's good progress all the same... 8-)
