| 5 | Description: Arcturus Networks uC DIMM ColdFire 5282 |
---|
| 6 | ============ |
---|
[d5f0a05] | 7 | CPU: MCF5282, 64MHz |
---|
[572484f] | 8 | RAM: 16M |
---|
| 9 | ROM: 4M |
---|
| 10 | |
---|
[d5f0a05] | 11 | This is a credit-card sized board in a DIMM format. It is part of a family |
---|
| 12 | which includes Dragonball and Coldfire CPUs, with a standardized DIMM-based bus. |

| 16 | This BSP is based on the work of: |

| 21 | TODO: |
---|
| 22 | ===== |
---|
| 23 | Make a clean exit routine to return to Arcturus monitor |
---|
| 24 | |
---|
| 25 | The bsp relies on the Arcturus monitor to set up DRAM and all chip selects. |
---|
| 26 | This seems OK to me, but others may find it lame..... |

| 66 | Downloading the image to the board. |
---|
| 67 | =================================== |
---|
| 68 | |
---|
| 69 | The bootable image is generated by the make-exe target in the bsp makefile. It |
---|
| 70 | generates a simple stripped binary file which is downloaded over the ethernet |
---|
| 71 | port into RAM then executed or programmed into flash memory. |
---|
| 72 | |
---|
| 73 | 1) Power up the uC5282 board. A dump of some memory map is produced |
---|
| 74 | followed by a prompt. |
---|
| 75 | |
---|
| 76 | 2) type 'tftp<CR>' |
---|
| 77 | |
---|
| 78 | 3) Run 'tftp' on your host machine: |
---|
| 79 | tftp> binary |
---|
| 80 | tftp> connect www.xxx.yyy.zzz (You're ucDIMM's address) |
---|
| 81 | tftp> put someFile.exe |
---|
| 82 | |
---|
| 83 | 4) When the file has downloaded press the <ESC> key to terminate |
---|
| 84 | the uCDIMM tftp command. |
---|
| 85 | |
---|
| 86 | 5) Type 'goram<CR>' to start the downloaded program, or type 'program<CR>' |
---|
| 87 | to burn the code onto the uCDIMM flash. |
---|
