Sorry for the long-delay on this issue, I got tasked with other stuff, but thanks to your hint from the last e-mail, I think I might have found the root-cause to the problem. In include/asm-m68k/immap.h. #ifdef CONFIG_M5271 #include <asm/immap_5271.h> #include <asm/m5271.h> #define CONFIG_SYS_FEC0_IOBASE (MMAP_FEC) #define CONFIG_SYS_UART_BASE (MMAP_UART0 + (CONFIG_SYS_UART_PORT * 0x40)) /* Timer */ #ifdef CONFIG_MCFTMR #define CONFIG_SYS_UDELAY_BASE (MMAP_DTMR0) #define CONFIG_SYS_TMR_BASE (MMAP_DTMR3) #define CONFIG_SYS_TMRPND_REG (((volatile int0_t *)(CONFIG_SYS_INTR_BASE))->iprl0) #define CONFIG_SYS_TMRINTR_NO (INT0_LO_DTMR3) #define CONFIG_SYS_TMRINTR_MASK (INTC_IPRL_INT22) #define CONFIG_SYS_TMRINTR_PEND (CONFIG_SYS_TMRINTR_MASK) #define CONFIG_SYS_TMRINTR_PRI (0) /* Level must include inorder to work */ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ #define CONFIG_SYS_TIMER_PRESCALER (((gd->bus_clk / 1000000) - 1) << 8) #endif According to MCF5271 RefMan Rev 2 (07/2006) page 13-12, I think this means that the interrupt, although unmasked, have a level 0, priority 0, which essentially disables it. What should be the proper value? (0x09) will make it level 1, priority 1, is this ok? Or am I chasing the wrong rabbit? Thanks for your time - Richard _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
