Hi all, I want port U-Boot to M5282Lite board.
To it create a new target in U-Boot Makefile and create the directory boards/m5282lite and include/configs/M5282LITE.h based on M5282EVB.
Also added the SDRAM init code to initdram().
These is my main defines:
TEXT_BASE = 0xFFE00000 #define CFG_LOAD_ADDR 0x20000 #define CFG_FLASH_BASE 0xffe00000 #define CFG_MONITOR_BASE (CFG_INT_FLASH_BASE + 0x400)
Using the m68k-bdm-elf-gdb I am trying to start u-boot:
(gdb) target bdm /dev/bdmcf0 Detected V2 core GDB target bdm connected to /dev/bdmcf0 Coldfire debug module version is 0 (5206(e)/5272/5282) (gdb) symbol u-boot Reading symbols from u-boot...done.

(gdb) b cpu_init_f Breakpoint 1 at 0xffe04638: file cpu_init.c, line 178. (gdb) c Continuing. ^ C [New process 42000]
Program received signal SIGTSTP, Stopped (user). [Switching to process 42000] 0xffe0808a in do_bootm (cmdtp=0xffffffff, flag=-1, argc=-1, argv=0xffffffff) at cmd_bootm.c:345 345 printf (" Uncompressing %s ... ", name); (gdb)
But it never goes to cpu_init_f ...
Am I doing some misconfiguration or some wrong step?
Cheers,
Alan
