Hello everyone,
I am seeking help to create a DTS file for my device so that I can build OpenWrt firmware v23.05.5 for it. Below are the details of the device:
Device Information:
- Device Name: DAVOLINK GAPD-7200
- Chipset: IPQ4018-OVV
- Components:
- SKY85405
- SKY1185303
- QCA8075 OVV (Ethernet Switch)
- WINBOND 25N01GVZE1G (NAND Flash)
- ESMY F25L16PA (SPI Flash)
- NANYA1824 (RAM)
Hardware Features:
- LEDs: 9 LEDs
- POWER
- WIFI 2G
- WIFI 5G
- WAN
- LAN1, LAN2, LAN3, LAN4
- WPS
- Ethernet Ports:
- 5 Ethernet ports (1 WAN + 4 LANs)
- All ports support 1Gbps speed.
- Buttons:
- 1 Reset button
- 1 WPS button
- Additional Ports:
- USB Port
What I’ve Tried:
I attempted to create a DTS file myself but unfortunately, all my efforts have failed. I am not sure what I am missing, and I would greatly appreciate guidance or a working DTS file for this device.
Purpose:
The goal is to enable me to build and flash OpenWrt firmware for this device successfully.
Any help, examples, or advice would be greatly appreciated. If you need any further details or logs, I will be happy to provide them.
Thank you in advance for your support!
