SPL "FV corrupted" error when loading EDK2 firmware from MMC partition for visionfive 2

[gopavarammanojkumarreddy]

Configuration

• Using: starfive_visionfive2_defconfig

Problem

SPL reports "FindFfsFileAndSection: FV corrupted" at address 0x40840000 and "dwmci_s: Response Timeout"

Environment

• Hardware: StarFive VisionFive2 (JH7110 RISC-V)
• Bootloader: U-Boot SPL 2021.10
• Firmware: EDK2 JH7110.fd (9MB)

What I've Verified

1. FV header exists at offset 0x840000 in firmware file
2. Firmware padded to exactly 9MB
3. Flashed to partition 2 (starts at sector 8192)
4. hexdump shows valid _FVH signature and FDT marker

Question

What could cause SPL to report "FV corrupted" when the FV structure appears valid? Is this a memory alignment issue, MMC read problem, or firmware structure mismatch?
