RSS Bot Posted November 9, 2023 Share Posted November 9, 2023 Description media: fix firefly-rk3399 mini-pcie slot. Problem description: The 3G/4G module is not available on the firefly-rk3399. According to the schematic, the "MINI PCIE" on the firefly-rk3399 only has USB2 functionality. Comparing with the official kernel device tree, it is found that the vcc3v3-3g-regulator power supply node is missing. However, the pins used by this node conflict with the leds node referenced in the kernel device tree for roc-rk3399-pc. This node is redundant in firefly-rk3399, so it is defined as "node deletion". Summary of modifications: Added vcc3v3-3g-regulator power supply node. Defined node deletion. How Has This Been Tested? [x] Successfully built. [x] System startup. [x] The USB2 functionality of "MINI PCIE".
