Hardware Rework Guide for MIMXRT1040-EVK and Murata M.2 Module

This section is a brief hardware rework guidance of the Edgefast Bluetooth PAL on the NXP i.MX MIMXRT1040-EVK board and the Murata’s 1XK, 1ZM or 2LL solution - direct M.2 connection to Embedded Artists EAR00385 (1XK), EAR00364 (1ZM) or EAR00500 (2LL) M.2 modules.

The hardware rework has two parts:

  • HCI UART rework

  • PCM interface rework

  • Wake pin rework

Hardware rework

  1. HCI UART rework

    • Solder R93 and R96

  2. PCM interface rework

    • Solder R70 and R79; remove R76 and R86; Connect J80.

  3. Wake pin rework

    • When using 2LL M.2 module, remove R456 and R457 to avoid the module has an impact on boot configuration.

Note: Make sure to disconnect J80 when debugging. Otherwise, the debugger downloading fails.
