For the switches, x is down (on this diagram), o is up and X
|
| 54 |
|
|
will be both.
|
| 55 |
|
|
|
| 56 |
|
|
There is also a ribbon cable from the CPU board to the serial
|
| 57 |
|
|
connectors. Orient this cable so that the red stripe connects
|
| 58 |
|
|
to pin R1 and is at the bottom of the CPU board. Directions
|
| 59 |
|
|
are in the hardware installation guide, but this part wasn't
|
| 60 |
|
|
terribly clear to me.
|
| 61 |
|
|
|
| 62 |
|
|
1. Bring up the existing Fujitsu board monitor.
|
| 63 |
|
|
|
| 64 |
|
|
Attach a serial cable to the top serial port - 38400/8N1.
|
| 65 |
|
|
Make sure that SW1-1 (X above) is up.
|
| 66 |
|
|
Turn on power. You will also have to press the RED button.
|
| 67 |
|
|
|
| 68 |
|
|
2. Download RedBoot into the FLASH.
|
| 69 |
|
|
|
| 70 |
|
|
Using the attached programs (minicom has a terrible time
|
| 71 |
|
|
with ASCII downloads - use these instead), download the
|
| 72 |
|
|
frv.ROM image. Use these commands
|
| 73 |
|
|
|
| 74 |

At this point, send the file frv.ROM using simple ASCII protocol.

Since minicom does this poorly, I use the attached 'dl_slow' script.
|
| 94 |
|
|
I set up minicom like this:

You'll know if the file is being transferred correctly by the LEDs doing a
|
| 117 |
|
|
little address dance (i.e. they are showing the address being loaded).
|
| 118 |
|
|
|
| 119 |
|
|
When the download completes, you may need to hit 'enter' a couple of times.
|
| 120 |
|
|
Then you should see:
|
| 121 |
|
|
Write Start...
|
| 122 |
|
|
Write OK!
|
| 123 |
|
|
Verify Start...
|
| 124 |
|
|
Verify OK!
|
| 125 |
|
|
Complete !!

|

|
|
|
| 130 |
|
|
At this point, change SW1-1 to be down (x). Press reset (the bottom blue
|
| 131 |
|
|
button on the CPU). You should get:
|
| 132 |
|
|
|
| 133 |
|
|
+FLASH configuration checksum error or invalid key

Notes:
|
| 148 |
|
|
|
| 149 |
|
|
* There are two FLASH devices on the motherboard. Using SW1-1, they swap
|
| 150 |
|
|
memory addresses. We use one (IC7) and the Fujitsu loader uses the other.
|
| 151 |
|
|
I see no reason (ATM) to replace the Fujitsu monitor other than to let
|
| 152 |
|
|
RedBoot be the primary. This way, reverting SW1-1, at least you can always
|
| 153 |
|
|
reprogram RedBoot.
|
| 154 |
|
|
|
| 155 |
|
|
CAUTION!! Do not change SW1-1 until after you've programmed RedBoot. If
|
| 156 |
|
|
you do it beforehand, you'll overwrite the Fujitsu monitor.
