Dasharo compatible with MSI PRO Z690-A and PRO Z790-P - development
Intro
This document gather various notes and documentation useful for development of Dasharo compatible with the MSI PRO Z690-A and PRO Z790-P platform.
Hardware connection
Requirements
- peripherals listed in the:
- RTE
- Sonoff S20 Smart Plug with custom firmware
Serial debug
- Attach the jumpers in
J16header to enable headerJ18according to the table below:
| Jumper position (TX) | Jumper position (RX) |
|---|---|
| EXT + COM | EXT + COM |
- Connect signals from the
J18header to serial receiver:
| RTE | Msi Z690 |
|---|---|
| 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.
SPI
- 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 control
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
| RTE | MSI Z690-A/Z790-P |
|---|---|
| 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
Connect SeaSonic FOCUS Plus Platinum power supply unit to the mains via
Sonoff S20 Smart Plug. To power control via RTE, Sonoff smart plug
