Occasional ContributorAGFB014R24B2E2EV : Evaluation board not booting with NAND Daughter card
Dear Experts,
We have received the new AGFB014R24B2E2EV Eval board, when we powered on the board the HPS Linux booting observed on UART, when Out of box experience daughter card plugged in . When we plug in the NAND Flash daughter card no prints are observed.
Please help.
Thanks

Hi,
Is the eMMC schematic the same as this?:
MK_086Hi @EBERLAZARE_I_Intel ,
Our development is in progress.
However, we are interested to test this on EVM. Looking forward to your input to make Linux booting from eMMC flash.

Hi,
I haven't done booting on Agilex lately and not to mentioned NAND. Let me check with our internal experts and I shall get back to you.
In theory, I believe other than ARM DS which will use the hps_debug.jic. Then, there could be an FPGA boot first, but I still need to check with our internal experts:
I will let you know any updates soon.

HI @EBERLAZARE_I_Intel ,
Will await for your response.
We have our custom design with eMMC flash. Though EVM has this but there were no boot prints observed when NAND daughter card is plugged in by selecting eMMC flash memory.
Thanks

Hi,
For the NAND booting, assuming the NAND has been flashed upon shipped, need only to change the MSEL to QSPI upon power up:

Can you share the QSPI boot logs that was working?

Hi,
True, we are also assuming the NAND has been flashed upon shipping and selected the MSEL to QSPI. But no boot prints from the NAND daughter card. We selected NAND and eMMC flash on that daughter card, but still, no prints were observed from both memory.Is there any way to program NAND flash without the ARM DS tool?
Attached is the QSPI boot log.
Thanks

Hi,
"QSEL change from OOBE card.", is that typo, u mean using QSPI card it is able to print and boot?

Hi,
Try to Set MSEL to QSPI (AS) at Page 30:

Hi @EBERLAZARE_I_Intel ,
Yes, the MSEL to QSPI was selected as per the document but still, no prints were observed from the NAND daughter card. Prints were seen with this QSEL change from OOBE card.
Thanks
