Hi,
We are using DM8148CCYE2 with TPS659113 in our board with other ASICs , FPGA.
I have few very queries regarding power up sequence of TPS659113.
I referred DM8148 EVM. In that power up sequence is such that 1.8V,3.3V,1.5V(DDR), 1.35V
1.According to EVM Hardware user guide to achieve the power-up sequencing of 1.8V,1.5V (DDR),3.3V,1.35V (mentioned in datasheet)
When using TPS659113
GPIO 0 should be connected to 3.3V power supply enable
GPIO 7should be connected to DDR power supply enable (GPIO 7 will come up first according to the sequence mentioned in hardware user guide , and DDR rail should be connected to it.But in EVM GPIO 0 is connected to DDR power supply enable and GPIO 7 is connected to 3.3V power supply enable).
Which one is correct . Please confirm
2.Core voltage required for my processor is 1.35V. Whereas in EVM its 1.2V. How to change the configuration in EEPROM. Is it possible to program EEPROM foe new configuration
