We want to use the CFI driver for all U-Boot Flash operations. Our board design uses 2 Intel 16-bit wide StrataFlash chips wired in "parallel". But with the following defines in place, flash_init() crashes (attachment). #define CFG_FLASH_CFI #define CFG_FLASH_CFI_DRIVER #define CFG_FLASH_PROTECTION None of the U-Boot docs or source code describe a parallel chip configuration, but the flash_cfi.h history entry does suggest its support: 01/22/2004 - Write performance enhancements for parallel chips The source also checks the status of info->interface for a value of FLASH_CFI_X8X16. I have not yet tried setting this "interface" value. If anyone can suggest any other settings that I should be pay attention to, please advise. Thank you, Andy -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
