Hello Community,

I want to changed RJ45 to FO is it Possible in TI-RTOS ?

If yes, Where changes are required, I mean in which Code/Stack Changes are Required ?

Hi,

Yes it is possible! Please check the http://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_board.html#custom-board-addition for how to customize with your own board. In your case, it will be changing the PHY to Fiber optics. The code is under pdk_am335x_1_0_xx\packages\ti\board\src\<AM335x_BOARD>\device. You must have your own software doing the FO configuration as transceiver.

Hi Community,

As per below thread it is possible.

e2e.ti.com/.../3097044

So the Question is to support fibre optic in RTOS in which block/stack changes are required and why?

I have attached software block diagram of RTOS.

Pankaj

Pankaj,

If a PHY e.g. DP83822 allows connection to fiber optic transceiver, the change is mainly in hardware bootstrap configuration, see Table 11. Modes of Operation in DP83822 datasheet.

If you need replace a PHY, e.g. TLK110 which doesn't support fiber optic transceiver, addtional change need to be done in the 'Board Library' shown above block diagram, as Eric referred to pdk_am335x_1_0_xx\packages\ti\board\src\<AM335x_BOARD>\device.

Hi Garrett,

Thanks for your response.

Where is hardware bootstrap configuration ?

Any expected changes in PRU-ICSS firmware ?

Pankaj,

Hardware bootstrap configuration is described in the section 8.5.1 - http://www.ti.com/lit/ds/symlink/dp83822i.pdf

No change is required in PRU-ICSS firmware.

Garrett

Garrett ,

Did you mean hardware changes required ? ,No Software or RTOS-SDK changes required for Hardware bootstrap configuration eg. Board Library ?
