Unable to boot device into maskrom mode


#1

Hello,

I am running Mac OS 10.14.3, trying to boot my Rock960c into maskrom mode to flash Debian onto the eMMC. (I have two boards, one with embedded eMMC and one with removable eMMC).

For my board, I hold down the maskrom button, then press the reset button. The board is connected to my Mac via USB-A to USB-C. When I run, lsusb, the device is not recognized:

Is there a firmware that my Mac device needs to recognize Rock960 devices?

I was able to boot the device into maskrom mode using these instructions https://www.96boards.org/documentation/consumer/rock/installation/linux-mac-rkdeveloptool.md.html
