Hi, I met a strange problem on FLASH programming with BDI2000 on a 8xx board.After programming a 11.7MB ramdisk to 4*8bit Intel FLASH[4*28F128J3A=64MB],the main menu of application in ramdisk couldn't appear.But if I did this job with U-BOOT,everything went well.Also the ramdisk programmed by BDI2000 was checked "right" as following with crc32 by U-BOOT.Meanwhile,I have been using BDI2000 good for programming U-BOOT and Linux kernel.So weird... I hope this is not a bug of BDI2000 fireware... Could anyone encounter such strangeness before?
