Some channel configurations may not restore from persistent memory

Applies To:

Firmware for GRV-R7-I1VAPM-3
Firmware for the following groov EPICs:

GRV-EPIC-PR1
GRV-EPIC-PR2

Versions Affected:

For GRV-R7-I1VAPM-3: 3.3.0 to 3.4.1
For groov EPICs: All versions prior to 3.5.0

Resolved In Version:

For GRV-R7-I1VAPM-3: 3.5.0
For groov EPICs: 3.5.1

Symptoms:

One or more I/O channel configurations may not be restored correctly from persistent memory after resetting a GRV-R7-I1VAPM-3 module or a groov EPIC processor through either of these methods:

In groov Manage, you click System > Restart.
You cycle power on the GRV-R7-I1VAPM-3 module or groov EPIC processor.

The issue occurs in the following situations:

For GRV-R7-I1VAPM-3 modules, you configure channels through groov Manage. The issue is more likely to occur if the module was recently reset to defaults.
For groov EPICs, you write through the memory map an invalid channel type to a channel that was previously configured with non-default values.

Workaround:

Do one of the following:

Configure the I/O channels using PAC Control.
Through the memory map, explicitly configure the channel's type (memory map address 0xF0100004 for channel 0) to a valid value.
