I am not able to reproduce this issue on a CM3588 NAS Kit, and looking
at the schematics the only diff seem to be LPDDR4X vs LPDDR5.

Above is from using tag v2026.01-rc2 with only a single USB stick
connected to one of the 3 USB-A ports on the board, using the reset
button between each test to ensure a clean state.

Do you have any other peripherals attached to your board when you test?
E.g. PCIe/NVMe, HDMI, Ethernet or similar?

For my test run above I only had 12V power-in, SD-card (with u-boot) and
Debug UART connected to my CM3588 NAS Kit board.

Also what DDR-init fwver and TF-A (BL31) are you using?

Jonas
