I am using PicoMOD7A. I would like to informe you that when I configure buildroot with picomod7a_min_defconfig and I compile it using fs-toolchain-4.7.2-armv6-vfp it doesn't work, the ubifs fimage generated doesn't work and the PicoMOD7A doesn't start.
But if I compile it using fs-toolchain-4.6.3-armv6-vfp, everything work correctly.
Has anybody had the same problem? Is there any solution for this issue?
