Hi there. I'm having a problem with the gdb stubs. Could it have something to
do with the gdb being 5.3 ?
I can't get a good compiled/linked library to work with my current gdb and the
aeb-1 (ARM7 with a sharp cpu with 256KB of flash and RAM)
After I do:
----------------------------------------------------------------------------
* "ecosconfig new aeb stubs"
----------------------------------------------------------------------------
changed the startup to "ROM"
* cdl_component CYG_HAL_STARTUP {
user_value ROM
};
----------------------------------------------------------------------------
* changed the include gdb stubs so that the script generates a good uuencoded
version to send
cdl_option CYGBLD_BUILD_GDB_STUBS {
user_value 1
};
----------------------------------------------------------------------------
* and after a make I get a 'good' uuencoded image

After I send it to ecos, the module appears in the boot:
----------------------------------------------------------------------------

After I plugin the module and try to run it simply does not work.
Even after I changed the serial speed from 38400 to 115200 I always get this
string in the buffer:
----------------------------------------------------------------------------
$T050°:04920104;0:60830100;#°3
----------------------------------------------------------------------------
This is the normal string from the old gdb.
----------------------------------------------------------------------------
$T05thread:00000000;0f:10870104;0d:908e0000;#95
----------------------------------------------------------------------------
This seems like a good gdb string but gdb simply doesn't like it

And for 115200 and lower speeds also no luck.
The main reason for this change was to change the speed of the serial port
from 38400 to 115200 because the download time was getting big.

----------------------------------------------------------------------------
Works well except the speed factor already mentionated.
Also I already have some drivers for maxim ADC, LCD and I2C and others
What do I need to get this included? The SPI/I2C by software and the graphical
routines for the LCD is done. Its a simple nokia display using SPI kind of
connection.
With best regards,
Carlos Sobrinho
PS: I have attached my export and ecos.ecc file
