Here's my issue : I had loaded the Flash memory of an electronic card with 2 RAMdisk which are supposed to be the same. However, when I checked the messages displayed on a screen at boot time, I observed that there were some differences between the 2 RAMdisk : > > Messages displayed for the 1st RAMdisk : > > ## Booting image at ffb00000 ... > Image Name: Linux-2.6.10_mvlcge401-8560ads > Image Type: PowerPC Linux Kernel Image (gzip compressed) > Data Size: 1662041 Bytes = 1.6 MB > Load Address: 00000000 > Entry Point: 00000000 > Verifying Checksum ...

Can someone help me to understand what is the root > cause of these differences, please ? Thank you very much for your help. Hi Erwan, I'm afraid this is absolutely not related to U-Boot. I can just offer the remark that iminfo shows your ramdisks differ in their rootfs part. If you have any additional question, feel free to e-mail me -- in private, to avoid noise on the U-Boot list. > Best regards, > > Erwan Gr?ce Amicalement, -- Albert.
