Hi,

I have an installation of four 9G20 boards connected to a single power source of regulated 5V - 2.5A which should be enough. The specs says that the board consumption is 0.4A, but when I power up the boards (i.e. turn the power supply on), all of the boards fail to boot, even to show the ROMBoot prompt.

If I connect them one by one, there is no problem at all, the power supply has enough current to power the 4 boards.

Is there any peak consumption at power up ? If so, how can I calculate the right power supply requirements ?

Regards,

Alejandro
