Dasharo compatible with MSI PRO Z690-A and PRO Z790-P - development
This document gather various notes and documentation useful for development of Dasharo compatible with the MSI PRO Z690-A and PRO Z790-P platform.
- peripherals listed in the:
- Sonoff S20 Smart Plug with custom firmware
- Attach the jumpers in
J16header to enable header
J18according to the table below:
|Jumper position (TX)||Jumper position (RX)|
|EXT + COM||EXT + COM|
- Connect signals from the
J18header to serial receiver:
|J18 pin 1 (GND)||JBD1 pin 1 (pin closer to JBAT1)|
|J18 pin 2 (RX)||JBD1 pin 2 (pin further from JBAT1)|
Pins on JBD1 are not described in the documentation. They have been discovered experimentally. Pay attention to the connections.
Please also note that this is uni-directional communication. We can gether logs from booting, but we cannot provide input to the platform at the same time.
- For external flashing, connect
RTEwith motherboard according to the table below:
|RTE SPI header||MSI Z690-A/Z790-P|
|J7 pin 1 (Vcc)||JTPM1 pin 1 (SPI Power)|
|J7 pin 2 (GND)||JTPM1 pin 7 (GND)|
|J7 pin 3 (CS)||JTPM1 pin 5 (RESERVED / BIOS SPI CS pin)|
|J7 pin 4 (SCLK)||JTPM1 pin 6 (SPI Clock)|
|J7 pin 5 (MISO)||JTPM1 pin 3 (MISO)|
|J7 pin 6 (MOSI)||JTPM1 pin 4 (MOSI)|
JTPM1 is a 2mm pitch header, you will need 2mm to 2.54mm female-female dupont wires to connect to RTE.
The JTPM1 pin5 is actually BIOS SPI CS pin (marked as reserved in the board manual).
- Example connection:
Power buttons control
Connect 12V/4A power supply to RTE J13 connector to power on RTE
Connect power control pins from mainboard to RTE according to the table below:
JFP1 is located in the corner of the mainbaord, near SATA interface ports
|J11 pin 9||JFP1 pin 6 (PWR_ON)|
|J11 pin 8||JFP1 pin 7 (RST)|
|J15 pin 1 (GND)||JFP1 pin 5 (GND)|
Power supply control
