I see in the qoriq-tseries.pdf show the T4240RDB using IR3565BMFS01TRP to supply 1.0V and 1.5V for T4240RDB, so I bought exactly new IC IOR with partnumber IR3565BMFS01TRP, but when I solder to my custom board and original T4240RDB, in both cases, it does not work. But if I use the old IR3565B IC which is in the original T4240RDB then the power 1.0V and 1.5V is ok. My question is How to program to IR3565B?
