How to build and install CygMon on the PID
|
| 39 |
|
|
|
| 40 |
|
|
Make CygMon image
|
| 41 |
|
|
~~~~~~~~~~~~~~~~~
|
| 42 |
|
|
|
| 43 |
|
|
Configure and build using the 'cygmon' template for the PID
|
| 44 |
|
|
target. These are the necessary CLI instructions. It can also be done
|
| 45 |
|
|
from the Configtool by selecting the appropriate templates.
|
| 46 |
|
|
|
| 47 |
|
|
% cd /tmp
|
| 48 |
|
|
% mkdir cygmon
|
| 49 |
|
|
% cd cygmon
|
| 50 |
|
|
% ecosconfig new pid cygmon
|
| 51 |
|
|
% ecosconfig tree
|
| 52 |
|
|
% make
|
| 53 |
|
|
|
| 54 |
|
|
This will install some files in ./install/bin:
|
| 55 |
|
|
|
| 56 |
|
|
cygmon.elf: The built CygMon image
|
| 57 |
|
|
cygmon.bin: The image converted to binary (suitable for burning to ROM)
|
| 58 |
|
|
cygmon.img: The relocated ELF image (suitable for FLASH writing, see below)
|
| 59 |
|
|
cygmon.srec: The image converted to srecords
|
| 60 |
|
|
|
| 61 |
|
|
Make FLASH tool
|
| 62 |
|
|
~~~~~~~~~~~~~~~
|
| 63 |
|
|
|
| 64 |
|
|
Again, these are the necessary CLI instructions. It can also be done
|
| 65 |
|
|
from the Configtool by selecting the appropriate templates, and
|
| 66 |
|
|
enabling the option.
|
| 67 |
|
|
|
| 68 |
|
|
% cd /tmp
|
| 69 |
|
|
% mkdir pid-flash
|
| 70 |
|
|
% cd pid-flash
|
| 71 |
|
|
% ecosconfig new pid

Prepare board for CygMon
|
| 91 |
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
| 92 |
|
|
1. Set jumper 7-8 on LK6 [using the Angle code in the 16 bit EPROM]
|
| 93 |
|
|
2. Set jumper 5-6 on LK6 [select 8bit ROM mode]
|
| 94 |
|
|
3. Set jumper LK18 [ROM remap - this is also required for eCos]
|
| 95 |
|
|
4. Set S1 to 0-0-1-1 [20MHz operation]
|
| 96 |
|
|
|
| 97 |
|
|
|
| 98 |
|
|
Program FLASH
|
| 99 |
|
|
~~~~~~~~~~~~~
|
| 100 |
|
|
1. Download the CygMon relocated image onto the PID board:
|
| 101 |
|
|
% cd /tmp
|
| 102 |
|
|
% arm-elf-gdb -nw cygmon/install/bin/cygmon.img
|
| 103 |
|
|
|
| 104 |
|
|
(gdb) target rdi s=

|
|
This will download the stubs onto the board at 0x60000..0x80000
|
| 120 |
|
|
|
| 121 |
|
|
Use /dev/ttyS0, COM1 or similar for the name.
|
| 122 |
|
|
|
| 123 |
|
|
2. Now download the FLASH programmer tool
|
| 124 |
|
|
% arm-elf-gdb -nw pid-flash/install/bin/prog_flash.img
|
| 125 |
|
|
|

|
(gdb) cont
|
| 140 |

|
| 141 |
|
|
3. The FLASH tool will output some text on the board serial port B at
|
| 142 |
|
|
38400 baud:
|
| 143 |
|
|
|
| 144 |

|
| 149 |
|
|
|
| 150 |
|
|
4. This text is repeated until you remove the jumper 7-8 on LK6. Then
|
| 151 |
|
|
the output should be:
|
| 152 |
|
|

|
| 156 |
|
|
*** Press RESET now to abort!
|
| 157 |
|
|
|
| 158 |
|
|
5. You have about 10 seconds to abort the operation by pressing
|
| 159 |
|
|
reset. After this timeout, the FLASH programming happens:
|
| 160 |

| 162 |
|
|
All done!
|
| 163 |
|
|
|
| 164 |
|
|
6. Quit/kill the GDB process which will hang.
|
| 165 |
|
|
|
| 166 |
|
|
7. Next time you reset the board, CygMon will be in control, communicating
|
| 167 |
|
|
on serial port A at 38400 baud. See documentation for further details
|
| 168 |
|
|
on how to connect with GDB.
