* [U-Boot-Users] how can I boot u-boot from 0x40000 in flash instead of 0x0000 @ 2005-07-14 19:56 Ray Zhao 2005-07-14 19:58 ` Wolfgang Denk 2005-07-14 20:03 ` Jerry Van Baren 0 siblings, 2 replies; 3+ messages in thread From: Ray Zhao @ 2005-07-14 19:56 UTC (permalink / raw) To: u-boot My board need keep the first 0x40000 flash for special purpose. Is it easy to modify the u-boot to load itself from 0x40000 instead from the 0x0000? Any help is appreciated.
