[U-Boot-Users] CFI driver status?
Hi good people!
I'm working with a modified AT91RM9200DK board with an Intel P30 CFI flash (JS28F128P30TD85 to be exact), and since I experience problems when doing buffer writes to the flash using u-boot 1.1.3, I've been scanning the mail archives for insights and help.
It turns out there are *NUMEROUS* patches and improvements floating around for the CFI driver, that aren't in CVS and many of them are even very old but appear to be addressing legitimate shortcomings.
Is there any collected effort anywhere on sorting out the issues with the CFI driver?
In my particular case, I can unprotect and clear sectors fine, but the flash never responds ready (status bit 7 set to 1) after I write a D0 (FLASH_CMD_WRITE_BUFFER_CONFIRM) in the buffer write sequence... :-O

Just to close this, it turned out our board was feeding the flash 3.3V instead of 1.8V and this made it respond in very funny ways... oops! ;-) Things look better now!
