Re: [U-Boot-Users] 16BIT SPANSION Flash writing problem with CFI Driver
Hi,
I didn't enable buffer writes. Once I defined CFG_FLASH_USE_BUFFER_WRITE, all save operations would encounter an error. Actually, I noticed it was unaccptable to enable buffer write for AMD flash.
I guess you can implement CFG_FLASH_USE_BUFFER_WRITE for AMD style flash. The details is in the datasheet. It should speed up the programming anyway.
I use CFG_FLASH_USE_BUFFER_WRITE in my board with a Spansion S29GL032 Flash in 8BIT mode, and til now, it works perfectly.
This mode is the only one allowed in 8BIT mode, so I guess that it is acceptable for Spansion/AMD flashes
Best regards,
Alexandre

Glad to see your input on this point. My misleading understanding was from old notes in CHANGELOG. Should be updated this time. This way, the implementation of buffer writes support is an issue of 16-bit support.
Thanks,
Sam
