Re: exxos blog - random goings on
I get back "BFBF" as expected now. Its the ID from both flash chips at once on the bus (flash is 8bit wide so 2 chips used to get 16bit)
So it seems...
Data being written to the bus isn't actually valid until UDS/LDS go low
So actually reading the 68K datasheet...
So what I did was to delay the flash for a clock cycle, which basically simulates waiting for LDS,UDS going low.. THEN latch the data on the bus.. What would be happening before would be I would just be latching in 1's all the time as nothing would be driving the bus at that point
Incidentally, I had to use Keli's numbers , so he was right in that I needed to rotate some bits
So we are now talking to the flash

Well done - great work.
I just got one of the other RTC / Flash (Flashy Clock) boards working, sockets and pins are the biggest PITA ever.

Welcome to the Socket Haters Society..
If it ain't broke, test it to Destruction.
Re: exxos blog - random goings on
Was wondering when youd notice it
I might see if I can fit that key to one of my STs. Think it came from a Dragon 32, cant remember.

Re: exxos blog - random goings on
I thought about that but it took me 30 mins just to make it small enough to fit in the 12k required
If it ain't broke, test it to Destruction.
Re: exxos blog - random goings on
Oh, I can increase the size to 20k or whatever...

Re: exxos blog - random goings on
Done a quick flash routine..
Only writes to address 0, I need to program up the erase sectors routine next to clear the full banks which will hold TOS next.
