Hi All, We have built u-boot (from git as suggested by U-Boot SPARC / LEON Port v 1.0.0 April 2009. The building is successfull. I configured for execution in ram (CONFIG_SYS_TEXT_BASE = 0x40000000) and the system runs. But nothing I see on the serial console connected to minicom. When I do Crtl+C the system stop at an address inside such function: arch/sparc/cpu/leon3/cpu_init.c - void cpu_init_f(void) I found that it fails: /* Find AMBA APB IRQMP Controller */ if (ambapp_apb_first(VENDOR_GAISLER, GAISLER_IRQMP, &apbdev) != 1) { /* no IRQ controller, something is wrong * ==> jump to start (or hang) */ while (1) ; }
so the while (1) occurs.
I discovered that: ambapp_apb_first(VENDOR_GAISLER, GAISLER_IRQMP, &apbdev)
Any suggetions?
