[U-Boot] [U-BOOT PROBLEM] RAM loading RAMdisk addresses
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 :
## 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 ...

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.
Best regards,
Erwan Grâce

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

Please restrict your line length to some 70 characters or so. Thanks.

The are obviously different, as they have different sizes.
We cannot answer the "why" as we have zero information about what you did on that system, or why you even think they should be the same. These are two different files.
