Hello all,
My name is Erwan Grâce, I'm French. 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 :

As you can notice, the 2 RAMdisk seem to be different but I don't know why. I just observe that they have different size and they are not loaded at the same address in RAM memory. I precise that I didn't build this RAMdisk. 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 Grâce
