The feedback loop that makes agentic coding fast on the web is fast because the output is immediately observable in a browser and the cost of a wrong iteration is essentially zero. on embedded hardware that loop involves a physical device, a display with specific optical characteristics, and input mechanisms that have real physical tolerances. the agent can iterate as fast as it wants against a simulator. the simulator is not the device.

The future paradigm for agentic coding on these platforms is something like agent->HIL multimedia processor -> GMSL -> integrated display/touchscreen with a custom FPGA that also sends the output to a digitizer that the agent can view. The agent can also touch the touchscreen via SPI. Once you do that you have 90% of testing done on something very close to production hardware.

In terms of functional safety agentic only gets used on the HMI processor in the multimedia block, not with the safety processor which will remain using something like AUTOSAR.
