Hi everyone,
I recently got a Milk-V Jupiter and I’m currently stuck in a “no-boot” state. I’m looking for advice regarding power supply requirements before I proceed with deeper diagnostics.
**Current Status:**
-
Initial Setup: Attempted to boot Bianbu OS from a 500GB NVMe. It showed the logo once, then hung.
-
Current Symptoms: No status LEDs, no HDMI signal. However, TitanTools still recognizes the board in DFU mode.
-
Current PSU: 12V 4.5A (54W) wall adapter.
The Dilemma:
I’ve noticed some videos where the Jupiter can peak at 60W-66W during boot, especially with an NVMe attached. My current 54W adapter might be the reason for the initial crash and subsequent boot failure.
I have a 550W ATX Power Supply available and I just received a CP2102 UART adapter for debugging.
My Questions:
-
Is it safer/recommended to switch to the ATX PSU via the 24-pin connector before attempting to capture UART logs?
-
Is it possible that the 54W power drop corrupted the SPI Flash or put the PMIC in a “protect” state that prevents LEDs from lighting up?
-
Are there any known risks of using an older ATX PSU with the Jupiter board?
I would appreciate any guidance before I plug everything in. Thanks!
