Jasper 16, 256, 512 - how to tell?

[Martin C]

First time, when I got to flashing nandflash.bin and xenon.elf I had 2 errors writing block 21 and block 37. The console didn't boot and I remember I forgot to set the LDV in options.ini. Anyway, If the final nandflash image was not written on 21 and 37, I guess I must extract those blocks from nandflash.bin as bb1 and bb2 then write them manually to NAND, is that correct? This is what I meant with the post I'm quoting.

NO!

You do NOT need to mess with bad blocks at all once you have your CPU key.

As I said, use your original NAND dump and CPU key and put into multi_builder (or J-Runner of course).

Read the output log and you'll see that XeBuild deals with these bad blocks for you.

Martin as its a jasper do you think he should try the electrical tape method .? If you are wondering what I am refering to put tape on bottom of board and tape on top of wires to isolate them from board. Just my two pence worth thrown in here. But please listen to Martin he knows what he is talking about

FIXED !

I got an 47 nF capacitor(couldn't find a 68 nF one). Mounted between GND and A, tried to boot 10 times to XELL, got 10 working XELLs. & times, the boot was instant, 2 times tooked around 3-4 sec to load and one time took around 15 sec to load. BUT, all the time XELL loaded correctly, withoud freezing and artefacts.

DONE !

Wrote nandflash.bin and xenon.elf from usb stick and it boots first time to the dash.

Using the a capacitor of 68 nF(47 in my case) between GND and A did the trick.

Thanx guys !

Did you not get a cap in with the coolrunner?

If it's a rev. B coolrunner, there are two points (labelled 'cap') on it which you bridge to enable the 68nF cap.

:-|...didn't noticed that points, I just used an external cap...very dumb of me...

...when thinking about hard stuff...you're missing the simpliest ones...

Sometimes that bridge doesnt work. I had to solder external cap to make it work. I dont know why.

Tried to remove the external cap, bridged but it didn't worked, so, I soldered back the cap and works like a charm.
