Installation Instructions:
|
|
||||||
--------------------------
|
|
||||||
|
|
||||||
1. Put the s2 switch into the following position:
|
|
||||||
|
|
||||||
Off On
|
|
||||||
------
|
|
||||||
|x |
|
|
||||||
| x|
|
|
||||||
|x |
|
|
||||||
| X|
|
|
||||||
------
|
|
||||||
|
|
||||||
Put the s3 switch into the following position:
|
|
||||||
|
|
||||||
Off On
|
|
||||||
------
|
|
||||||
| x |
|
|
||||||
| x |
|
|
||||||
| x|
|
|
||||||
| x|
|
|
||||||
------
|
|
||||||
|
|
||||||
Put the s4 switch into the following position:
|
|
||||||
|
|
||||||
Off On
|
|
||||||
------
|
|
||||||
|x |
|
|
||||||
|x |
|
|
||||||
|x |
|
|
||||||
|x |
|
|
||||||
|x |
|
|
||||||
| x|
|
|
||||||
| x|
|
|
||||||
|x |
|
|
||||||
------
|
|
||||||
|
|
||||||
2. Connect to the serial console and to the BDI. Power on. On the
|
|
||||||
serial line, you should see:
|
|
||||||
|
|
||||||
PURPLE@1.2>
|
|
||||||
|
|
||||||
3. Type '8'. No echo will be displayed. In response, you should get:
|
|
||||||
|
|
||||||
7A(pass)
|
|
||||||
|
|
||||||
4. From BDI, enter command:
|
|
||||||
|
|
||||||
mmw 0xb800d860 0x0042c7ff
|
|
||||||
|
|
||||||
5. Then, from BDI:
|
|
||||||
|
|
||||||
erase 0xB0000000
|
|
||||||
erase 0xB0008000
|
|
||||||
erase 0xB000C000
|
|
||||||
erase 0xB0010000
|
|
||||||
erase 0xB0020000
|
|
||||||
|
|
||||||
prog 0xB0000000 <u-boot.bin> bin
|
|
||||||
|
|
||||||
6. Power off. Restore the original S2 switch position:
|
|
||||||
|
|
||||||
Off On
|
|
||||||
------
|
|
||||||
| x|
|
|
||||||
| x|
|
|
||||||
|x |
|
|
||||||
| X|
|
|
||||||
------
|
|
||||||
|
|
||||||
Power on. U-Boot should come up.
|
|
||||||
|
|
||||||
|
|
||||||
Implementation Notes:
|
|
||||||
---------------------
|
|
||||||
|
|
||||||
Due to the RAM/flash bus arbitration problem the suggested workaround
|
|
||||||
had to be implemented. It works okay. On the downside is that you
|
|
||||||
can't really check whether 'erase' is complete by polling flash as it
|
|
||||||
is usually done. Instead, the flash driver simply waits for a given
|
|
||||||
time and assumes that erase then has passed. This behaviour is
|
|
||||||
identical to what the VxWorks driver does; also, the same timeout (6
|
|
||||||
seconds) was chosen. Note that this timeout applies for each erase
|
|
||||||
operation, i. e. per erased sector.
