Clarifications Required for i.MX RT1170 EVKB

Dear NXP Team,

Greetings!

We are planning to use the i.MX RT1170 MCU, starting with the EVKB board, for one of our upcoming projects. The project will involve integration of a 4G data module, Ethernet, camera, audio, and display. I have a few technical queries and would appreciate your guidance on the following:

1. 4G Data Module Configuration
We would like to use a 4G module with the EVKB board.

Is it correct to insert the SIM card into the on-board slot and connect a 4G modem (e.g., Quectel EC25) via the M.2 interface?
Which interfaces (e.g., UART, USB) are internally connected between the EVKB, SIM slot, and the M.2 connector?
Are there any SDK examples or application notes available for configuring and communicating with a 4G module through this interface?

2. Camera Interface and Remote Monitoring
Our requirement involves using a camera to stream video remotely, similar to a CCTV system.

Can the i.MX RT1170 EVKB support this use case?
What are the supported camera interfaces (MIPI-CSI, USB, etc.), and is there any reference code or documentation for camera integration and remote streaming?

3. Display Integration
We intend to use a display with either RGB-to-LVDS or MIPI-DSI interface to show full-screen videos, animations, and text.

Are there any SDK examples or reference guides for interfacing LVDS/MIPI-DSI displays?
What are the hardware/software requirements for rendering smooth video and graphics?

4. Audio Playback
The system should play voice prompts example like “Hello” or “Good Morning.”

We are considering using either an audio codec with the SAI interface or a DFPlayer module over UART.
Which method would be more reliable or recommended for this platform?
Are there any SDK examples available for SAI + codec configuration?

I would greatly appreciate your support and any reference documentation or sample projects you could share.

Looking forward to your kind assistance.

Thank you in advance.

Best regards,
Pandiyan T.

1.
Unfortunately, we do not have a test case to confirm this as the examples are for Wifi and Bluetooth. So I cannot confirm that inserting the SIM card will work with a 4g modem via M.2 interface. The board schematic shows that SIM card is directly connected to the RT1170.

M.2 connector interfaces with UART and SDIO.

2.
Yes, that application can be used however there is no example of streaming video. There are examples to acquire video through MIPI-CSI and trough USB.

i.MX 8/RT MIPI DSI/CSI-2

3.
Yes, please refer to the display examples on the SDK, as well as lvgl examples.
Please refer to this application note: AN12940: Use Case of RT1170 LCD Display System based on MIPI DSI – Application Note
Regarding the requirements, it may vary as the resolution would require certain amount of data.

4.
I don't know your requirements to choose which one to use, however, we have useful examples of SAI with the onboard codec. Please refer to any of SAI examples of the SDK, they use SAI along with the EVK codec.

BR,
Omar
