NXP Board EMAC Implementation
Budget: $750 – $1,500 USD
I need to bring up the on-chip EMAC on my NXP board so it can reliably handle data transmission over Ethernet using UDP. The hardware is already powered and running the latest NXP SDK; what’s missing is a clean, well-structured EMAC setup that can move payloads out of RAM and onto the wire with minimal latency and zero packet loss.
Scope
– Configure and initialise the Ethernet MAC, PHY, clocks, and relevant pins.
– Implement a lightweight driver or integrate the SDK’s EMAC layer, exposing simple send/receive buffers.
– Provide a concise demo that opens a UDP socket, pushes test data across the link, and echoes incoming packets so I can verify round-trip integrity with Wireshark.
Acceptance
• Link comes up automatically after reset with a valid DHCP-assigned or static IP (your choice, just document it).
• Continuous UDP traffic at 100 Mbps for five minutes without dropped frames.
• Source is clean C, builds in MCUXpresso (or plain Makefile) without warnings.
• A one-page markdown or PDF notes pin assignments, clock tree tweaks, and any errata-related work-arounds.
If you’ve tuned EMACs on NXP, STM32, or similar Cortex-M parts before, this should be straightforward. Looking forward to your approach and timing.
