Other Parts Discussed in Thread: DRV8353RS-EVM
Hello TI,
We are connecting our custom MOSFET power board with DRV8353RS Development board.
Trying to run the 24V BLDC motor by DRV8353RS board with our custom power board,
for interfacing we have removed the MOSFETS(Q1Q4,Q3Q6,Q2Q5) ,Shunt resistors(R14,R15,R16), and R55,R56,R57 also removed.
GHA,GLA,TP3 and GHB,GLB,TP2 and GHC,GLC,TP1 connections are taken out from DRV and connected with custom MOSFET power board.
DRV8353RS Development board voltage divider Resistor network only using for phase voltage measurement
for phase current measurement CURSEN_TYPE_INLINE_HALL (hall sensor) used and its available in Custom mosfet power board.
when run the code at Build level 1 Current offset measurement showing around 2000 and its expected one, for voltage offset measurement instead of 0.49 its showing 1.01,and voltage offset error occurred and Fault LED Getting ON while run the code.
In SPI Failure status register 1 and 2 also checked, there is no failure bit has set.
what would be the issue, reference images also attached here.
Thanks in Advance.
