I'm working with Manuel, he's out for lunch right now.<br>
<br>
We've checked out libmc1323 git, not the contiki branches. But seeing
both, the only difference is the TARGET_WITH_ROM_VARS variable.<br>
<br>
We came to this point because when using TARGET_WITH_ROM_VARS blink_led
wasn't working properly. So,<br>
we found out that the single line:<br>
<br>
<font face="Courier New, Courier, monospace">bl _rom_data_init+.-base</font><br>
<br>
is preventing our mc13224 from running.<br>
<br>
In the contiki branch, this line is allways being executed, and that's
why it does not work.<br>
In the libmc1323 branch, there is the option of disabling it if we
don't set TARGET_WITH_ROM_VARS, and that's why<br>
we are able to run some examples (blink, uart loopback..)<br>

<pre wrap="">Hi!
As I commented in other mails I was working in contiki examples and I
couldn´t get them working. I´ve been looking for the error during
several weeks, and I realized while trying to work rf-test (libmc1322)
that the problem is about ROM patching. When the example has to use ROM
VARS, it doesn´t work. The concrete instruction that makes it get
stalled is
#ifdef USE_ROM_VARS
bl _rom_data_init+.-base
#endif
The address of the jump instruction is:
.set base, .
.set _rom_data_init, 0x108d0
I´m using freescale 1322xSRB motes. Any idea of how to fix this, or
where can I find info of that address?

Ok, this is odd. I believe this use to be a problem a while ago... I'm
not sure why you are seeing it now.
rom_data_init is a ROM function that initializes ROM variables
allocated here:
.org 0x120
ROM_var_start: .word 0
.org 0x7ff
ROM_var_end: .word 0
in start.S.
In the versions of start.S in the branches that work right now,
(mc1322x-2.4 and WIP-2.4), there the line you sent is simply
bl _rom_data_init+.-base
and not
#ifdef USE_ROM_VARS
bl _rom_data_init+.-base
#endif
Can you veryify for me what you have checked out?
