RTOS/PROCESSOR-SDK-AM335X: Running Linux and RTOS

Nagamahesh Gamidi61

Part Number: PROCESSOR-SDK-AM335X
Other Parts Discussed in Thread: AM3358, SYSBIOS, AM3359

Tool/software: TI-RTOS

We would like to run TI-RTOS (SYSBIOS) through PRU and Linux-3.2 on AM335x at a time on AM3358 or AM3359.

Is this possible ?

If yes, is there any Hand shaking mechanism between TI-RTOS (SYSBIOS) PRU and Linux-3.2 on AM335x to send some data from micro controller to AM335x.

Linux kernel v3.2 is obsolete and no longer supported by TI. It is not possible to run Linux and RTOS concurrently on any AM335x device.

Thanks for the reply Biser.

Can we port TI- RTOS SYS/BIOS on PRU of AM3359 SOM ?

Can we run both linux-3.12 and TI-RTOS SYS/BIOS in am3358 and am3359 at a time?

Can we run both QNX and TI-RTOS SYS/BIOS in am3358 and am3359 ?

Actually our customer requirement is to run, QNX on AM335x and TI RTOS SYS/BIOS on PRU, is this possible ?

RTOS cannot run on the PRU. On AM335x devices you can run either Linux or RTOS on the ARM, but not both at the same time. Same is valid for QNX.

Can you please look into the below links and please let us know which RTOS is ported to PRUSS ?

No operating system is ported to PRU. The PRU can be loaded with firmware for a specific task, which interacts with the OS running on the ARM Host (Linux or RTOS).

PRU examples for RTOS include an Ethernet MAC, Ethernet Switch, Industrial protocol switch. This does not mean that RTOS is running on the PRU.

As for Linux, the wiki link you posted is detailed enough.

Can you please share some useful links.
