Roda RK9 Flash Header
|
||
|
=====================
|
||
|
|
||
|
There is a 5x2 pin, 1.27mm pitch header *J1* south of the BIOS flash. It
|
||
|
follows the pinout of the Dediprog adaptor board:

| 1 2 | 1: HOLD 2 2: CS 2
|
||
|
| 3 4 | 3: CS 1 4: VCC
|
||
|
| 5 6 | 5: MISO 6: HOLD 1
|
||
|
| 7 8 | 7: 8: CLK
|
||
|
| 9 10 | 9: GND 10: MOSI
|
||
|
+------+
|
||
|
|
||
|
Pins 3 to 10 directly map to the regular SPI flash pinout.
|
||
|
|
||
|
There is also a *JP17* around. Ideally, it should be closed during
|
||
|
programming (isolates the SPI bus from the southbridge):
