TDA4VM: How to generate random numbers in RTOS?

Zhengxing Qiao

Part Number: TDA4VM

I've successfully produced random numbers in QNX.

Can I generate true random numbers in RTOS?

Does the TDA4VM RTOS SDK have a function interface or method for generating true random numbers in RTOS?

Thanks.

Hi,

Unfortunately, RTOS does not have any module to generate random numbers. Can you please use the number generated from QNX?

So if I want to use random numbers in an RTOS, I can only get them by using IPC after QNX has finished booting?

This is correct. There is no support for random numbers in RTOS, you'll need to get them using IPC onmy
