Abstract

TDA4-EVM is a reference development platform with super set of peripherals to showcase the system-on-chip (SoC) capability. The customer develops board the based on the use cases that need to be supported on their platform. Typically, there is a cut down on the peripherals, change in the peripheral parts chosen, changes in the number of instances of a peripheral supported eventually leading to a different design. So, on top of the default SDK, the customer needs to implement custom pinmux, DDR, PMIC, console universal asynchronous receiver/transmitter (UART) related changes as per the board design. This application note addresses the changes needed on top of the SDK and describes the common issues encountered during a custom TDA4 board bring up.
