Hello Rolf,
Hello Sascha,
I tried your hints... but I don't get the prompt ">" after a while my
Desktop-PC say that a Ethernet connection is established thats all I can
not ping or connect to the pyhBoard-Wega-AM335x. But nothing is
transmitted on the Evaluation Board (PEB-EVAL-01). Do I need some
patches or something else?
Sorry but I have no idea which information I can send you to help me
with my problem...
Thanks again
Florian

Hello Rolf,
thank you very much...
after I selected the mentioned entry in the menu the problem was solved...
but the board do not prompt any thing on the UART1... so I do not
know if barebox is loaded
When using mainline barebox please build the am335x_mlo_defconfig for
the MLO and the am335x_defconfig for the main binary. The images
are then found under:
images/barebox-am33xx-phytec-phycore-mlo.img
images/barebox-am33xx-phytec-phycore.img
I diffed you config against the mainline config and the following
options are really crucial to let the binary work correctly:
-CONFIG_TEXT_BASE=0x0
-CONFIG_MALLOC_SIZE=0x0
-CONFIG_MALLOC_TLSF=y
-CONFIG_RELOCATABLE=y
+CONFIG_TEXT_BASE=0x402F0400
+CONFIG_STACK_SIZE=0x1600
+CONFIG_MALLOC_SIZE=0x1000000
in fact, these settings are essential.
If you still can't see anything, you can also enable the config item "Debugging"
-> "low level debug messages". With this option enabled, you should at least see
a '>' on UART1 right after power-on. This character will be output at the end of
function pcm051_board_init().
If you like to debug the further startup, you could also enable the "Debugging"
-> "Trace initcalls" option in barebox_mlo config.
Best regards,
Rolf
