Problems with Auto-Initialize on DMA & MIBADC1 RAM

Lacrecia Ruman-Roe

I am having problems getting the DMA and MIBADC1 RAM to auto-init. The rest of the RAM modules complete successfully. Even ADC2, so I don't understand why ADC1 does not. What do I have to do to get the DMA and ADC1 to complete initialization?

I have powered-up all peripherials and enabled them prior to running this code.

// enable memory hardware initialization

p_PSR->u32_MINITGCR = (uint32)0x0000000AU;

p_PSR->u32_MSINENA = (uint32)0x0000177F;

// Wait for memory hardware initialization to complete

while(((p_PSR->u32_MSTCGSTAT) & (uint32)0x00000100) != (uint32)0x00000100){} ;

// disable memory hardware initialization

p_PSR->u32_MINITGCR = (uint32)0x00000005U;

Thanks,

Lacrecia,

Just a fundamental question so that we can syncronize .

1. What the TI Micro Part number you are using .

2. What other RAM other than MibADC RAM you were able to sucessfully initialize?

Best Regards,

Pratip

We are using the TMS570 LS20216-ASZWTQQI.

I was able to initialize

RAM, MIBSPIPs, DCANs, and NHET

Thanks,

I was able to get this working. Seems I was using the wrong bit fields in the MSINENA for the ADC and DAM.

Thanks,
