Flashing: Orange Pi 5B

Flash method: rkdeveloptool via pv-flash-bundle (eMMC) — see rockchip.md

Image artifact: pv-flash-bundle-orangepi-5b.tar.gz (eMMC) or pantavisor-starter-orangepi-5b*.wic.gz (SD card)

Build: kas build kas/build-configs/release/rockchip-orangepi-5b-scarthgap.yaml — see the build config table.

Hardware overview

The Orange Pi 5B is a Rockchip RK3588S SBC (4×Cortex-A76 + 4×Cortex-A55) with on-board eMMC and Wi-Fi/Bluetooth. The BSP comes from JeffyCN/meta-rockchip (kas/platforms/rockchip.yaml).

Two USB-visible connectors matter for flashing:

Connector	Use
USB-C	Power and the USB OTG port rkdeveloptool talks to
Maskrom button	Small button next to the USB-C / headphone jack; hold it to force USB Maskrom mode

SD card boot

pantavisor-starter-orangepi-5b*.wic.gz boots straight from a microSD card with no eMMC changes. Write it per SD Card and insert it; the RK3588S boot ROM tries SD before eMMC. Good for evaluation without touching eMMC.

rkdeveloptool (USB flash to eMMC)

1. Enter Maskrom mode

1. Power the board off; remove any bootable microSD card.
2. Hold the Maskrom button.
3. Plug the USB-C cable into your host.
4. Release the button after ~2 s.

2. Flash

Using the self-contained bundle (recommended — no rkdeveloptool install needed):

tar xzf pv-flash-bundle-orangepi-5b.tar.gz
cd pv-flash-bundle-orangepi-5b
./flash.sh

flash.sh waits for the Maskrom device, sends loader.bin to SRAM, writes the whole .wic from sector 0 (GPT + idbloader + U-Boot + rootfs), and reboots. See Flashing Rockchip devices for prerequisites (libusb-1.0, udev rule) and troubleshooting.

3. Boot

The board reboots from eMMC automatically after rkdeveloptool rd. Remove the USB-C cable and re-attach power if it was only USB-powered.

Notes

• Keep no bootable microSD card inserted while flashing — rkdeveloptool wl 0 writes to the first storage the loader enumerates, which should be eMMC but can be the SD card if one is present.
• The build produces .wic.gz + .wic.bmap; only the .wic.gz is used by flash.sh.
