SD Card Boot

@JingyangTeh_Altera

I encountered the issue for 2025 and i switched to 2024.07 to confirm all basic function sanity.

Now i am switching back to settle the 2025.01 or 2025.04 issue on the boot for Cyclone V.

Same situation that after the message:

"

U-Boot SPL 2025.01-gcd3a9044d661-dirty (Sep 01 2025 - 08:57:07 +0800)
Trying to boot from MMC1

"

I had study short on that document and if not wrongly understand.

The A2 partition is no longer use?

The U-Boot is a must to use Jtag or QSPI or Flash based chip to store the 1st boot data?

It is possible to change to A2 partition like 2024.07?

Thank you
