There is an issue in the reset circuit of the AM335x EVM schematic. AM335x PWRONRSTn signal should be driven by VDDSHV6 power supply voltage level (1.8 V or 3.3 V) although it's driven by VRTC (1.8V) in the schematic. Please use VDDSHV6 voltage level for PWRONRSTn when you design your schematic. The reset circuit will be updated for fixing the issue in next AM335x EVM schematic release.
Hello,
We need some advice on the PWRONRSTn connection in AM335x.
The datasheet says that VIH for PWRONRSTn is 2V.
But it is different in the EVM, the PWRONRSTn input is connected to the AND Gate(U1A)
which has its Vcc connected to VRTC (i.e.1.8 volts)
So we wonder this may meet the datasheet specification.
Please let us know if the EVM Schematics is wrong or we missing something.
Regards.
