it was set but I will check again as I may have "unset" it with my experimentation. Thanks for the tip.

EDIT:  It was not set but I have reset it, but still no cigar.

Raspberry Pi / Re: Probleme loading extension

« Last post by imaad on July 23, 2014, 01:25:18 AM »

I use many raspberry in the same time with the same type of SD card. Not all the raspberry have this problem even if I re-power multiple times. But when this problem appear in one of the raspberry this will be permanently almost on each re-power. Sometime to avoid this problem, because it becomes annoying, I must rewrite the image on SD card.

If the SD card is unreadable why the kerner boot all the time and just the extension have this problem ? Or the SD card has same partition broken and the kernel and extension don't start correctly ?

SD card can be unrealible, not only corrupted or demaged. Did you try another SD card?

Is the boot flag set?
You can use cfdisk or gparted to toggle it.

Thanks Yin. I have been trying different things since my last post and have  left 1 Mb before the primary partition. Still wasn't having any joy when I discovered that Grub2 does not work with ext2. Have reformatted with ext4 and the grub-install command worked without a hitch, reporting "no errors" when it finished. However the pc still won't boot. I have been playing with the BIOS settings using UEFI then disabling it and using legacy boot. To no avail. I'm still not sure how grub sees the flash memory; as a floppy, SD card, USB stick or HDD? My original install parameters were wrong too so I changed the command to: "grub-install --boot-directory=/mnt/mmcblk0p1/boot  /dev/mmcblk0".

SD card corruption? Use the showapps bootcode to see how far it gets.

Raspberry Pi / Probleme loading extension

Hi,

I have a problem when the system try to load the extensions. The system show that it load the extensions (because status bar rotate continuously) but it never pass this step.
This is not all the time just from time to time. Sometime I must re-power the raspberry 4-5 times until the extensions can be loaded.
Anyone knows why?

Thank,

Probably you did not leave enough free space between the start of the drive and the start of the partition. You should leave at least 1MB.

That is not the correct place.
When you have problems with things not working correctly, don't expect us to help troubleshoot it.
