4. How to Make the SPRD U25 Diag Driver Work (Step-by-Step)

Prerequisites:

• A U25-based device (check with getprop ro.board.platform → should return ums8581 or uis8581).
• A USB cable capable of data (not charge-only).
• Windows 10/11 64-bit (or Ubuntu 20.04+ for Linux).

• ADB-like access for debugging and shell/fastboot-like operations
• Serial/console access to kernel logs (dmesg)
• Flashing firmware (via factory/loader tools)
• Access to diagnostic interfaces (modem logs, QXDM-like functions)

Typical Work Scenarios

• Field return analysis – Extract crash logs from non-booting devices.
• RF calibration – Modify NV items for radio tuning.
• Firmware development – Step through bootloader or RTOS tasks.
• Production testing – Automate diagnostic queries to verify hardware.
