MPC5606B error

khaleadpark — Thu, 10 Jul 2014 13:36:06 GMT

Hi. I have TRK-MPC 5606B board.

I have a problem.

Error:

Illigal operands 'volatile union' [ 'unsigned char'

Code:

void vfnInit_normalconversion_adc(unit8_t u8ChannelType, unit32_t u32Channel)

{

ADC_0.CTR0[u8ChannelType].R = 0x00008606;

.......

}

[u8ChannelType] → error

Please help me. Please.....

Thank you.

Khaled

Hi Khalead,

I'm not sure if this lines makes sense?

ADC_0.CTR0[u8ChannelType].R = 0x00008606;

From the reference manual there are 3 CTR registers, were you meaning?

ADC_0.CTR[u8ChannelType].R = 0x00008606;

Can you tell us what exactly you are trying to achieve with that line?

Thanks,

Ian

Hi Khalead,

Thanks for all the information but I think the error:

Illegal operands 'volatile union' [ 'unsigned char'

is trying to say that the CTR0/1/2 registers can't be accessed as an array with u8ChannelType as the index. In fact the text:

/* Note the following CTR registers are NOT implemented as an array to */

/* try and maintain some concistency through the header file */

/* (The registers are however identical) */

kind of backs this up!

I work with the PPC MPC55xx, 56xx and 57xx daily but I don't use the Freescale header file with all the registers defined, so I could be wrong with the interpretation of the error you are seeing!

I'll check my implementation when I'm at work on Monday :-)

Thanks,

Ian

Hi Khalead,

This is the implementation I use:

#define ADC_0_CTR (*(volatile unsigned long *) 0x<register address>UL)

And then perhaps something like:

int index;

volatile unsigned long *adc_ctr = &ADC_0_CTR;

for (index = 0; index < 3; index++) {

adc_ctr[index] = <value>;

}

Hope it helps :-)

Thanks,

Ian
