Everything is working fine until a flash write access is performed using MTD. After this a (soft) reboot stucks in mpc5xxx_restart() where the watchdog timer is charged and linux waits with closed interrupts until the MPC performs the reset. Only power off helps in this situation. It seems to me like a hardware problem, because the freescale MPC5200lite reference board does not run into this. The main difference of the custom board to the reference board is, that it is using 16MB Intel Strada Flash instead of AMD flash, which has an erase block size of 128kB. Has anybody else experienced such behaviour? Arno Geissel
