OMG is this thing tiny
I managed to enter maskrom mode using a chopstick but unfortunately my ‘Linux computer’ with USB-C does not exist or could be only a Linux VM in macOS with USB passthrough.
At least the board appears on the USB bus:
USB 3.1 Bus:
Host Controller Driver: AppleIntelCNLUSBXHCI
PCI Device ID: 0xa36d
PCI Revision ID: 0x0010
PCI Vendor ID: 0x8086

Can you please point to the correct rkdeveloptool repo and confirm whether this works with arm64 as well or only x86/x64?
