Hi,
I just figured out that my PC target was failing to boot,
because I upgraded the compiler from (buildroot toolchain) gcc-4.8.x to
gcc-4.9.x
The configuration is:
BR2_TARGET_GRUB2_I386_PC=y
BR2_TARGET_GRUB2_BUILTIN_MODULES="boot linux ext2 fat part_msdos
part_gpt part_bsd normal biosdisk sleep echo video videoinfo help jpeg
uhci ehci usb usb_keyboard usbms usbtest gfxterm gfxmenu vbe vga
video_bochs video_cirrus font search search_fs_file search_label test
test_blockarg keylayouts at_keyboard cat configfile loadenv eval serial
regexp"
(I know, that makes a lot but work like a charm with gcc-4.8.2)
The symptom is :
-------------------------------
'' is already set
Aborted. Press any key to exit.
-------------------------------
After some (printf) debugging, I found out that when 'loading' the
builtin modules at startup, some modules names are corrupted.
I am about to get into deeper investigation, but has anyone
encountered it ?
Best regards
Thierry
