Hi all
I tried to run u-boot-1.1.6 on my old MBX860 board (Version 20C). I tried several version but I always get the same behavoir. No communication on the serial line. Only when I press a key on my keyboard I get a strange string back (for example RETURN give the ASCII code 170 back "¬")
What have I done:
1) build own GNU environment ( I follow for this the guideline from Dan Kegel). I did that in cygwin under Windows XP 2) then download u-boot-1.1.6 3) make CROSS_COMPILE=powerpc-860-linux-gnu- MBX_config --> works fine 4) make CROSS_COMPILE=powerpc-860-linux-gnu- all --> works fine with a few warnings 5) I use the EPPC of the MBX to download the u-boot.bin and flash it with "pflash 4000:xxxxxxxx fc000000 6) I can check the entries of the flash with md fc000000 and their I see some text like "u-boot Version 1.1.6" --> so flash is written 7) Then I set the jumper J4 to 2-3 but then I got this strange behaviour.
I set in include/configs
#define CONFIG_MPC860 1 /* This is a MPC860 CPU */ #define CONFIG_MBX 1 /* ...on an MBX module */
#define CONFIG_8xx_CONS_SMC1 1 /* Console is on SMC1 */ #undef CONFIG_8xx_CONS_SMC2 #undef CONFIG_8xx_CONS_NONE #define CONFIG_BAUDRATE 9600 /* Define this to use the PCI bus */ #undef CONFIG_USE_PCI
#define CONFIG_CLOCKS_IN_MHZ 1 /* clocks passsed to Linux in MHz */ #define CONFIG_8xx_GCLK_FREQ (40000000UL) /* --> my MBX has only 40MHz */
Any Idea why I do not see the startup dialogue of the u-boot bootloader ?
