PROCESSOR-SDK-AM335X: Ethernet Booting

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

Hi!

I am using Sitara AM3358 processor on custom board.

My client needs to flash the code through Ethernet. For this, processor has to boot through Ethernet. Could you help me in this matter?

Is there any GUI required or any Ethernet Bootloader is there?

Secondly, client wants to control the booting either through RS422 or Ethernet to flash the code. As I can see in TRM there is no option available in which all booting devices(UART, Ethernet, NAND) are available. We can't put switches to the unit due to some safety standards. Is there any solution for this?

Regards,

Gaurav

Hi,

Are you trying to do this with RTOS or Embedded Linux?

Thanks,

Max

Max,

One unit is Bare Metal.

Another unit is based on RTOS (VxWorks OS).

In both unit, client needs Ethernet booting as well as UART booting.

Hi Gaurav,

I've assigned this to an ethernet baremetal/RTOS expert. They should respond to this soon.

Thanks,

Ethernet boot & flashing aren't supported in PRSDK.

For a list of supported PRSDK boot modes please see: https://software-dl.ti.com/processor-sdk-rtos/esd/docs/06_03_00_106/AM437X/rtos/index_Foundational_Components.html#boot-modes

Also please see this e2e thread: https://e2e.ti.com/support/processors/f/791/t/916465

The only approach I can think of is a custom SBL. This custom SBL would be downloaded via the peripheral boot procedure, and could be controlled via RS422 or Ethernet. For details on the peripheral boot procedure, please see the AM335x TRM (spruh73q.pdf), 26.1.6 Booting.
