Advisory GPIO: Pins GPIO38 and GPIO46 Cannot be Used for Functions Other Than USB

Revision(s) Affected 0

Details Pins GPIO38 and GPIO46 can only be used as USB0VBUS and USB0ID. GPIO and

other functions are not available.

Workaround(s) None. This is fixed in Revision A silicon.

Advisory GPIO: GPIOs on Port C Do Not Toggle Correctly When Using the GPCTOGGLE

Revision(s) Affected 0

Details GPIOs on Port C do not toggle correctly when using the GPCTOGGLE register because

of a dependency on the state of GPIOs on Port A.

Workaround(s) Use GPCSET and GPCCLEAR registers or the GPCDAT register to toggle Port C

GPIOs.

This is fixed in Revision A silicon.

Advisory GPIO: Cortex-M3/C28x Reads GPIO State as ‘0’ When the GPIO is Mapped to the

Other Core

Revision(s) Affected 0

Details The Cortex-M3 core reads the GPIO state as ‘0’ when the GPIO is mapped to the C28x

core. Conversely, the C28x core reads the GPIO state as ‘0’ when the GPIO is mapped

to the Cortex-M3 core.

Workaround(s) None. This is fixed in Revision A silicon.
