BQ40Z80: Mapping the SLEEP flag to GPIO

ThomasP

Part Number: BQ40Z80

Hello,

I use the BQ40z80 EVM and have the same problem with mapping the SLEEP flag to any GPIO. The Pin 20 is high even if the System is in SLEEP Mode (Bus Timeout: 10s)
I also try to map the PRES flag [0:0:0:0] to the Pin 20 without any problem!

Can you help me please?

Many Thanks
Thomas

Can you share the gg file when you see the problem with the SLEEP flag? We would like to check your settings.

Hello Thomas,

This issue is due to a bug in the firmware of the BQ40Z80. There's currently no fix/workaround for this issue.

I apologize for the inconvenience.
