Dear sir,
My customer read the Firmware from the TI EVM（TI Controller TPS536C7B1）and download to customer‘s system（TI Controller TPS536C7B1）,But customer system is unable to boot after controller enable Pin pull high.
Customer’s debug steps are as bellows:
1. The peripheral circuit of customer‘s controller is same as the peripheral circuit of TI EVM controller;
2. The GUI can communicate normally with controller;
3. The Controller VDD 1.5V reference, PWM tri-states, CS reference voltage are normal;
4. Some registers can be modified;
5. but Some registers can not be modified by GUI; such as (EEh) MFR_SPECIFIC_EE (PIN_DETECT_OVERRIDE);
6. The GUI is abnormal. Such Vin reporting is 5.5V, Vin UV threshold is 4.5V,but GUI report Vin UV;
7. Customer’s application is rail A: Vin=4-6V, phase=6 (PWM1-PWM6), Fs=1.2MHz, Vo=0.8V (Modify Vo by GUI).
8. Can TI help to provide a firmware to power system?
you can send it to me, jack-li@ti.com
Regards,
Jack
