Yes the cable is strong enough. I think, it's a problem with the regulation of the RP4 and the 5V/4A power supply. I will test this power supply (5V/5A) later. I have more reserves there and can regulate the output voltage. https://www.meanwell-web.com/content/files/pdfs/productPdfs/MW/Rs-25/RS-25-s...

Hi, I looked at the schematic and the data sheets. The switching regulators are designed for 5.5V. The new USB specification allow a maximum of 5.5V. So can I assume that I can use 5.5V at pin 4/6? The background of the question is, I am using the NanoPi with the NMVe hat on 1 SSD on a USB3 port. Wi...

The problem has disappeared. No more problem with the emmc. I think, it was a problem with the software.
Thanks for your help.

I use a power supply 5V/4A for the NanoPi M4v2 who was connect on GPIO1 pin 4/6. The PS has 5,35V (with a SSD on USB and NMVe between 5,1V and 5,3V . How much is the maximum voltage for VDD_5V?

Hi, I get a new NanoPi 4Mv2. It was mounted on the heatsink and boot from eMMC. Unfortunately he boots very reluctantly from the eMMC card. If the Pi is cold, there is no change that it boots. It simply hangs itself during the boot process. Since the Pi is a bit warmer the boot process works sometim...
