Hi,

I'm trying to debug the FlexPWM of MPC5744P with S32D 2017.R1, I want to see the registers about FlexPWM, so I used "EmbSys Registers" to check those registers, but I found something wrong, following pictrues shown my code and some registers:

You can see the value of FlexPWM0_INIT_sub0 is 0xE0C0, but the value displayed by the EmbSys Registers is 0x0000, and this problem also happened on other registers which are adjacent. 

But the function of the code is realized, so what happened about the IDE or something else?

Thanks for any assistance.

Best regards,

Max Lee

  Hi Max,

  Could you try to enter a value into SUB0_INIT manually in Embsys registers View?

  BR,

  Stan

  I have the same problem. It looks like an Endian problem as these registers are 16 bit and all the flexPWM registers are swopped. The processor is Big Endian, compiler and assembler is also set-up for Big Endian and the header file is Big Endian, but the alignment looks like to be Little Endian. If I write to a register manually in Embsys registers View the value changes and the value is correct if I move my mouse over the value in the code, but if the value is changed in the code it changes the wrong register.

  Regards,

  Pierre
