I am running a TE0715, and would like to pass information from the FSBL to uboot as described in the "MAC Address Usage" App Note (see link below). Where is the fsbl_hooks.c that uses shared memory to pass environment variables to uboot?

Hi Steve,
you found the modified fsbl in the hdmi reference project:

or with prebuilts:

John,
I looked at the hdmi reference project and did not see the shared memory access. All that I saw was the following TODO comment in fsbl_hooks.c at about line 185:
/********************************************************************/
// TODO
// eth_init(XPAR_PS7_ETHERNET_0_DEVICE_ID);
Is there something that I am missing?
Thanks,
Steven
Hi,
sorry, my mistake! The FSBL of the hdmi project is only modified for hdmi design support.
The modifications for MAC are currently not available for the TE0715, but it will be done in the near future.

the HDMI demo FSBL does only include the HDMI init and not the full u-boot ethernet mac shared memory solution. We are in the process to add the uboot and petalinux configs also into out ref design, then the FSBL would get update also.
