How to build and install CygMon on the PID
Make CygMon image
~~~~~~~~~~~~~~~~~
Configure and build using the 'cygmon' template for the PID
target. These are the necessary CLI instructions. It can also be done
from the Configtool by selecting the appropriate templates.
% cd /tmp
% mkdir cygmon
% cd cygmon
% ecosconfig new pid cygmon
% ecosconfig tree
% make
This will install some files in ./install/bin:
cygmon.elf: The built CygMon image
cygmon.bin: The image converted to binary (suitable for burning to ROM)
cygmon.img: The relocated ELF image (suitable for FLASH writing, see below)
cygmon.srec: The image converted to srecords
Make FLASH tool
~~~~~~~~~~~~~~~
Again, these are the necessary CLI instructions. It can also be done
from the Configtool by selecting the appropriate templates, and
enabling the option.
% cd /tmp
% mkdir pid-flash
% cd pid-flash
% ecosconfig new pid
% <edit ecos.ecc, enabling the CYGBLD_BUILD_FLASH_TOOL option:>

% ecosconfig resolve
% ecosconfig tree
% make
The flash tool is installed in ./install/bin
Prepare board for CygMon
~~~~~~~~~~~~~~~~~~~~~~~~
1. Set jumper 7-8 on LK6 [using the Angle code in the 16 bit EPROM]
2. Set jumper 5-6 on LK6 [select 8bit ROM mode]
3. Set jumper LK18 [ROM remap - this is also required for eCos]
4. Set S1 to 0-0-1-1 [20MHz operation]
Program FLASH
~~~~~~~~~~~~~
1. Download the CygMon relocated image onto the PID board:
% cd /tmp
% arm-elf-gdb -nw cygmon/install/bin/cygmon.img
(gdb) target rdi s=<serial device>
Angel Debug Monitor V1.04 (Advanced RISC Machines SDT 2.11a) for PID
Built with Serial(x1), Parallel, DCC
Rebuilt on Apr 7 1998 at 22:20:43
Serial Rate: 9600
Connected to ARM RDI target.
(gdb) load
Loading section .rom_vectors, size 0x60 lma 0x60000
Loading section .text, size 0xeea8 lma 0x60060
Loading section .rodata, size 0x304c lma 0x6ef08
Loading section .data, size 0x7f8 lma 0x71f54
Start address 0x60060 , load size 75596
Transfer rate: 5548 bits/sec.
(gdb) quit
This will download the stubs onto the board at 0x60000..0x80000
Use /dev/ttyS0, COM1 or similar for the <serial device> name.
2. Now download the FLASH programmer tool
% arm-elf-gdb -nw pid-flash/install/bin/prog_flash.img
(gdb) target rdi s=<serial device>
Angel Debug Monitor V1.04 (Advanced RISC Machines SDT 2.11a) for PID
Built with Serial(x1), Parallel, DCC
Rebuilt on Apr 7 1998 at 22:20:43
Serial Rate: 9600
Connected to ARM RDI target.
(gdb) load
Loading section .rom_vectors, size 0x60 lma 0x4000
Loading section .text, size 0x4964 lma 0x4060
Loading section .rodata, size 0x384 lma 0x89c4
Loading section .data, size 0x28c lma 0x8d48
Start address 0x4060 , load size 20436
Transfer rate: 5449 bits/sec.
(gdb) cont
3. The FLASH tool will output some text on the board serial port B at
38400 baud:
ARM eCos
FLASH here!
manuf: 8, device: 40
Error: Wrong Manufaturer: 08
... Please change FLASH jumper
4. This text is repeated until you remove the jumper 7-8 on LK6. Then
the output should be:
manuf: 1F, device: A4
AT29C040A recognised
About to program FLASH using data at 60000..80000
*** Press RESET now to abort!
5. You have about 10 seconds to abort the operation by pressing
reset. After this timeout, the FLASH programming happens:
...Programming FLASH
All done!
6. Quit/kill the GDB process which will hang.
7. Next time you reset the board, CygMon will be in control, communicating
on serial port A at 38400 baud. See documentation for further details
on how to connect with GDB.
