"This is the problem," Mira said to her junior, Sam. "RDK-B's HAL (Hardware Abstraction Layer) was written for wl (Broadcom's proprietary ioctl interface). It expects things like wl -i eth6 status . The Qualcomm driver speaks iw and nl80211 . It's like handing a French menu to a chef who only speaks Japanese."

For a non-native SoC, you must bridge the gap where pre-built drivers and BSPs (Board Support Packages) are missing: How to Achieve RDK-B Integration with Non-Native Wi-Fi SoCs The Qualcomm driver speaks iw and nl80211
The standardized C interface (APIs) that the middleware calls to execute hardware-level actions.
