Latest data sheet (spru614f) is the following descriptions.
(2) The initial CVDD voltage at power on must be 1.00V nominal (for CYGA2 and CYG4 devices) or 1.05V nominal (for CYG and CYG2
devices) and it must transition to the AVS target value adjusted by a AVS driver. This is required to maintain full power functionality and
reliability targets specified by TI.
Our customer uses CYG2 devices and TPS40400 for power supply supply of CVDD(AVS), and TPS40400 becomes the 1.00V setting.
I think that you must do voltage setting at 1.05V.
However, the voltage setting becomes 1.00V in AVS of the most recent version of DVRRDK.
Must I really assume the nominal voltage 1.05V?
When soft setting of AVS is 1.05V, and fixed number setting of TPS40400 works in 1.00V and the state with the difference, will a problem be given?
I ask you a question for confirmation getting off with only update of the software simply.
In addition, please tell me if there is patch information.
