does i.mx91 support rt-thread with smart version ?

Hi NXP,

I can't find i.mx91 to support RT-Thread with Smart version, but i.mx6ull can.

We need i.mx91 to support RT-Thread with Smart version, can you help to check does NXP support this RTOS in the future ? If can, when the BSP will be released ?

Thanks very much.

Hello @jimmyli

I hope you are doing very well.

The i.MX91 does not support rt-thread.

Best regards,

Salas.

Dear salas,

Got it.

Thanks.

BTW, RT-Thread is very popular in China, and i.mx6ull has supported.

But some higher products need new MPU with better A core to support RT-Thread RTOS.

So, I am looking forward to finding that NXP will migrate RT-Thread to i.mx91.

Thanks again.
