Hello,

I am new to ARM programming and C. I have a task to create device to
measure temperature, display it in LCD and send it trough USB to PC. I
have:

1. OpenOCD toolchain ('Winarm' named as I understood) All is latest
versions, but Eclipse is 3.2, not 3.3
2. Olimex's SAM7-H64 with AT91SAM7S64
3. Olimex's ARM-USB-OCD

I took an led blink example from manual "Using Open Source Tools for
AT91SAM7S Cross Development" and modify it to read ADC and put this
value into LCD. Now I am trying to implement USB in my project.

When I was investigating software for ARM programming, I have compiled
BASIC USB project code in IAR and modifyed it to sent to computer char
'A'. And it work good. I get 'A' in computer.

Now I have investigated all posible examples trying to compile it in
WinARM, but it useless. They have problems during compilation beacuse of
makefile. Some times they need dependance files, some times something
also. Then I decided to port my IAR old code into my project. And I get
'compilable' code. Uploaded into MC but enumeration does not happens.

I do not understand why. Maybe because of makefile (modified manual's
version, very simple in comparation of another examples) Or maybe I have
to write something in crt.s file... I do not know.

Please, help me Give advice what to do I have no ideas to try.
The project is http://www.bulkin.info/download/ADCLCDUSB.zip
You can just import it in Eclipse.

Not enough information given to help with this.

What is the "IAR code"? Is it some kind of example included in the EWARM
package? AFAIK IAR includes a adapted version of Atmel's AT91 USB codes.

So you did not port the Startup-code from IAR- to GNU-assembler? Did you
compare the codes? Maybe extensions are needed. Did you check if
"structure packing" is needed? Did you adapt the settings for packing
and maybe alignment? Did you check if there are flags set in ISR's which
are also accessed by the main-loop but are not declared with volatile
(it seems the IAR compiler is more tolerant about missing volatiles)?

Hello, Martin

Thank you for your reply! I realy appricate it.

Unfortunetly I am just starter. I do not know what is "structure
packing" etc.
Yes, I should read some manulas, do step-by-step tutorials to understand
everything. But it will take a lot of time wich I do not have. Thus to
solve  my current tasks I just take examples and modify them. This is my
way to study and to  quick start.

According this logic I decided to try again to compile and start Basic
USB example, but for WinARM this time.

I hope, with your help I will start it ant after that implement it into
my project. I took at91sam7s64_basicusb_20060901_public. Import it into
Eclipse under WinXP. Delete PC exec directory, HTML, SrcIAR, USB.ewd,
USB.ewp, USBSam7.eww.

Move makefile in root directory, open it and change SHELL = sh to SHELL
= cmd
Everything from AT91SAM7S-BasicUSB move to root directory.

Try to compile Have problems with some pathes. Move all from src to
root. Compile. Have about 100 errors. Wrong patchs.

Move all from SrcWinArm to root. Compile Have 5 errors.
Here are:

fatal error: opening dependency file .dep/main.o.d: No such file or
directory
fatal error: opening dependency file .dep/interrupt_Usart.o.d: No such
file or directory
fatal error: opening dependency file .dep/dbgu.o.d: No such file or
directory
fatal error: opening dependency file .dep/cdc_enumerate.o.d: No such
file or directory

And also
No rule to make target `../compil/SrcWinARM/Cstartup_SAM7.c', needed by
`../compil/SrcWinARM/Cstartup_SAM7.o'. in console

And now I do not know what I have to do. :( The 'google' gives me
nothing.

First of all: try to build outside eclipse, just from the command-line
with make all. Do you still get errors?

I made attempt. The results in cmd window:

C:\workspace\mi>make all
System can not find described patch (translated from Russian by me)
ECHO mode is swithed off (translated from Russian by me)

I used make 3.81. Just copy it to C:\workspace\mi
