[ECOS] Startup Procedure

[ECOS] Startup Procedure

[Samer Darras]

I was able to build and run a Redboot image on AT91SAM7S256 successfully
and downloaded it to Flash using SAM-BA, but when I build any of the
sample programs using a default eCos configuration, it does not run. I
have tried creating a RAM linker script and use Redboot to run it;
however, that did not work either.

Should there be a specific startup sequence to make any of the sample
programs run?

Thanks.

I wound not suggest using redboot on the AT91SAM7S256. It does not
really have enough ram for it to be useful.

The AT91SAM7S devices are designed to run there applications from
Flash, not RAM. That is why there is no support for RAM startup in the
HAL. The test programs should just work. Burn them into flash and run
them.

I have tried a default configuration and compiled in the "serial.c"
example program and burned it to flash but it did not run. Nothing was
output on the serial port??? Is there anything specific in the default
configuration that I need to set or unset?

Thanks.

Why serial.c example program?

The default configuration will not have the interrupt serial device
drivers compile in.

A better tests programs to start with are
install/tests/hal/common/current/tests/*

They should always work.

RE: [ECOS] Startup Procedure

Still does not work????
These are the exact steps:
- Built a default configuration using the configuration tool
- Built the tests using the configuration tool
- Converted the test program "basic" to binary file using: 
arm-elf-objcopy -O binary basic basic.bin
- Burned the image into flash using SAM-BA
- Connected to serial port and was expecting to see a couple of message
after reset but nothing at all!!!!

Any other suggestions?

Thanks.

Where in flash are you programming it?
Which serial port are us using? What board rate?

At some point you are going to need a JTAG emulator so that you can
debug. You might want it earlier rather than later so you can single
step through the startup code and work out what is happening.

At address 0x100000 and the serial port/debug port are both set to 2
just like RedBoot @ 38400bps and redboot works just fine. I think it is
time to fire up the JTAG emulator then!

Thanks.

It is working now! Somehow the debug output went out on port 1. Thanks,
Andrew for your help.

Thanks.
