Hi Ben,
I'm not sure if this has been mentioned or not. You should be able to read/write the flash from the BDI-2000, regardless of whether you connect the LA or LBA address bits. The difference comes into play when you want to boot from the flash chip. During the very early boot process, only the special LSbits toggle.
Yeah, I'd read that in some corner of the processor reference manual, and fired up the MDS board with a logic analyzer just to confirm it. I wondered at the time how many people would miss that subtle requirement!
On one spin of our board we missed this as well, and had to do some funny business with an I2C EEPROM to boot the board. Thankfully it was easy with our CPU (MPC8349) because it only involved programming a couple of configuration words and no UPM programming like Dave H. has suggested.
Ah-ha, so it is possible - cool :)
(crossed fingers it won't happen to me though ...)
Have you tried asking Freescale for help through their website? I've found their tech support in these matters to be responsive and useful.
Yep, I second that. Freescale's design support is great. Sometimes they confirm what you don't want to hear ... but they do respond quickly :)
Cheers, Dave
