<br><font size=2 face="sans-serif">Hi all</font>
<br>
<br><font size=2 face="sans-serif">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.</font>
<br><font size=2 face="sans-serif">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 "¬")</font>
<br>
<br><font size=2 face="sans-serif">What have I done:</font>
<br>
<br><font size=2 face="sans-serif">1) build own GNU environment ( I follow
for this the guideline from Dan Kegel). I did that in cygwin under
Windows XP</font>
<br><font size=2 face="sans-serif">2) then download u-boot-1.1.6</font>
<br><font size=2 face="sans-serif">3) make CROSS_COMPILE=powerpc-860-linux-gnu-
MBX_config --> works fine</font>
<br><font size=2 face="sans-serif">4) make CROSS_COMPILE=powerpc-860-linux-gnu-
all --> works fine with a few warnings</font>
<br><font size=2 face="sans-serif">5) I use the EPPC of the MBX to download
the u-boot.bin and flash it with "pflash 4000:xxxxxxxx fc000000</font>
<br><font size=2 face="sans-serif">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</font>
<br><font size=2 face="sans-serif">7) Then I set the jumper J4 to 2-3 but
then I got this strange behaviour.</font>
<br>
<br><font size=2 face="sans-serif">I set in include/configs</font>
<br>
<br><font size=2 face="sans-serif">#define CONFIG_MPC860
1
/* This is a MPC860 CPU
*/</font>
<br><font size=2 face="sans-serif">#define CONFIG_MBX

<br>
<br><font size=2 face="sans-serif">#define CONFIG_8xx_CONS_SMC1

<br><font size=2 face="sans-serif">#undef CONFIG_8xx_CONS_SMC2</font>
<br><font size=2 face="sans-serif">#undef CONFIG_8xx_CONS_NONE</font>
<br><font size=2 face="sans-serif">#define CONFIG_BAUDRATE

<br><font size=2 face="sans-serif">/* Define this to use the PCI bus */</font>
<br><font size=2 face="sans-serif">#undef CONFIG_USE_PCI</font>
<br>
<br><font size=2 face="sans-serif">#define CONFIG_CLOCKS_IN_MHZ
1 /*

<br><font size=2 face="sans-serif">#define CONFIG_8xx_GCLK_FREQ
(40000000UL) /* --> my MBX has only 40MHz */</font>
<br>
<br><font size=2 face="sans-serif">Any Idea why I do not see the startup
dialogue of the u-boot bootloader ?</font>
