|
||||||
|
|
||||||
|
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. 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 errase
|
||||||
|
operation, i. e. per erased sector.
