Part Number: AM2634

Is it possible to load OS into onboard flash (like QSPI flash) through JTAG without using SD card (using card reader) .

Will AM2634 support LINUX ?

Hi Bivin,

Thanks for your query.

There is currently no plans to support Linux on AM263x given we have only Cortex-R cores in AM263x. Sitara MPU processors like AM64x, AM62x which has Cortex-A supports Linux.

Regarding loading OS into Flash, yes, it is supported. Please refer to below

AM263x MCU+ SDK: Flashing Tools (ti.com)

Regards,

Prasad

For processors which support Linux, will the same tool be used for loading OS into flash through JTAG ?

Hi Bivin,

I would request to file new e2e ticket on AM64x to get more clarity. Below is my understanding -

For Linux Processors, flow can be slightly different as Linux involves file system and many times full file system can't be loaded on QSPI flash (given smaller flash size).

Hence, in Linux flow, usually we would have SD card where file system would be loaded with bootloader on QSPI flash.

Prasad

Can i run RTOS on the same (AM2634), have doubt since it is not listed in software development session. Does Ti RTOS support automatic multi-core management like Linux ?

Yes, FreeRTOS is supported on AM263x. You can refer to below section in user guide for features supported. Note, we dont support TI RTOS (but only FreeRTOS) in MCU+ devices.
