Re: PCM Hammer fails on P12
It would definitely be nice to have one ...

If I was here to win a popularity contest, their would be no point, so I wouldn't be here!

Uses 1mb chip but bin is 512kb, There is also some slave file $C000 size.
It looks like the second part of chip [upper 512kb bytes] are referenced in code, but can`t be read from memory. Maybe shared with other cpu or bankswitched somehow. The slave is also loaded somewhere. Starting at $10000 but again couldn`t figure yet where it is in memory layout.
A real dump of full chip will help alot how memory is organized.
SLave ram is at 80 00 00 address.
It can take multipart flash routines if they are between ffa000 and ffe000.
main cpu ID is 10
slave ID is 17
It also can take some slave flash routine that is loaded at ff8xxx and is max $600 bytes long. But seems unused with factory tools. Maybe some underground equipment ready.
Reading of 512kb bin part is easy. The main difference between ls1 reading is the COP, needs to keep slave quiet.

You know that is a P10 board right? I am still trying to get this P12 PCM opened up and see what's inside. I did post alot of information on the P10 earlier.
Re: PCM Hammer fails on P12
So, I fixed up a test, Darkman5001 ran it on a P12, the results ...
It's happily getting along,
PLEASE correct me (and those next to come along) if I'm wrong.
Thought I would try losing the 'size' from the request and see what happens, thus making the request,
Any other suggestions ??

You need to send only this, after pcm is unlocked.
P12 have different memory layout. try loading at ffff2000

Re: PCM Hammer fails on P12
edit: Ignore this quote, see the following two posts!
Duh!And, 34 80 on the last ??
I'll worry about the address after getting past the request ...

Re: PCM Hammer fails on P12
You send this to enable mode 36
6C 10 F0 34
the response will contain 44 if succesfull.
Than send mode 36 00 for upload only and 36 80 for upload and execute[last message]

kur4o,
I humbly apologize, that was all my mistake ... I know the the steps, I guess I was having a brain fart!
