Is it possible to program PL From linux running on PS after linux have booted up?

Hi,

Please provide TI part number and packages to support you.

Thank you.

hi,

the board is Zedboard and the part is Zynq (zynq xc7z020-clg484).

thank you

Hi Mohamad,

Your board info seems to be not a TI part or TI EVM.

We are helpless if you not have TI parts or TI EVMs.

I apologize for the inconvenience.

If you don't mind, I would like to suggest to use TI's OMAPL138 LCDK board which is very less cost ~195USD.

You can clarify your questions and problem with our TI E2E device forum as well general Linux forum.

hi Titusrathinaraj,

The board is not a TI part, but on this board we have parts from TI. i need help to adjust the voltage for my board through the UCD's. (TI UCD's)

I bought a Zedboard (with Zynq). This board utilized 3 pcs of UCD9248.

i need help, I want to know how i can adjust the voltage on the rails of this pcs using the command of PMbus.

and for that i post this question to control the power controller from the PS.

thanks

Hi Mohamad,

No worries.

You have to ask the zync processor support team for the software example code which would do PMbus protocol on their platform and adjust the voltage etc.,

Sorry, we can't help since we don't know about the architecture of that processor and also it is not in our support band.

I hope you can understand.

Xilinx grudgingly supports the Zedboard at their forum:

Xilinx has a fairly good Wiki

To load the PL from linux involves using the /dev/xdevcfg interface. Never used it myself. Usually just let the FSBL do it. Search for xdevcfg in the forums or wiki.
