Subject: [PATCH v2 6/6] arm64: dts: qcom: qrb2210: add dts for Arduino unoq
Date: Fri, 14 Nov 2025 13:18:53 +0100 [thread overview]
Message-ID: <20251114121853.16472-7-r.mereu@arduino.cc> (raw)
In-Reply-To: <20251114121853.16472-1-r.mereu@arduino.cc>
Arduino UnoQ is a single-board computer combining Qualcomm
Dragonwing™ QRB2210 microprocessor with STMicroelectronics STM32U585
microcontroller.
Support to a simply boot to shell environment includes:
- UART, I2C, SPI
- onboard LEDS
- eMMC
- WLAN and BT
