any reference code of serial rapidIO for MSC8151?

David_usami — Tue, 27 Aug 2013 02:49:28 GMT

I am a newbie for freescale StarCore DSP. Now I want to set up serial rapidIO between MSC8151 and an FPGA. I firstly want to configure serial rapidIO registers in MSC8151, and started setting up a loopback connection inside the DSP processor. But looks like it does not work as expected, DST address cannot receive any data. The following is the code. Anyone can help me fix it? Thanks!

int main()

{

UINT32 i;

INT32 bdid; // Target device id

/* configure SRIO ports */

MEM_WRITE32(RIO_P0CCSR, 0x50e00001); // Disable SRIO

MEM_WRITE32(RIO_P0ADIDCSR, 0x80010000); //alternate device id

MEM_WRITE32(RIO_P0ESCSR, 0xffffffff); // Reset status register

if(1) // loopback

MEM_WRITE32(PHY0_SRDSCR2, 0x008020c0); // enable loopback

else // back-to-back

// lane E/F transmitter equalization selection bus

MEM_WRITE32(PHY0_SRDSCR1, 0x11006630); // 1.33x relative amplitude

// disable SERDES1 SRDSCR2

MEM_CLR_BITS32(HSSI_CR1, 0x00000001);

MEM_WRITE32(RIO_P0CCSR, 0x50600001); // Enable SRIO (4x)

//---------------------------------

for(i=0;i<1024;i++)

{

*(UINT32 *)(SRC_ADDR+i) = i;

}

memset((void *)DST_ADDR, 0, 1024);

// checking that 4 lanes are synchronized and aligned

if(MEM_READ32(RIO_P0SLCSR) != 0xF0800000)

{

asm(" debug");

}

MEM_WRITE32(RIO0_BDIDCSR, 0x00FF0000); //configure as agent

MEM_WRITE32(RIO0_PGCCSR, 0x40000000); // set device as initiator (master)

// Configure Delta Outbound Address Translation Management Unit

bdid = 1 << SHIFT22;

MEM_WRITE32(RIO_P0ROWBAR1, (1<<20)|(DST_ADDR >> SHIFT12)); // +1

//MEM_WRITE32(RIO_P0ROWTAR1, (2<<20)|bdid | (DST_ADDR >> SHIFT12)); // target device id << 22

MEM_WRITE32(RIO_P0ROWTAR1, bdid | (DST_ADDR >> SHIFT12)); // target device id << 22

MEM_WRITE32(RIO_P0ROWAR1, 0x8004000f | (SWRITE << SHIFT12)); // for nread, nwrite

MEM_WRITE32(RIO_P0ROWTEAR1, 0x00000000); // large mode device id

// Configure Delta Inbound Address Translation Management Unit

// delta 1 goes to mbus 1 [by default value of RIO_P1RIWAR0 ] and delta 0 goes to mbus1 [RIO_P0RIWAR1]

MEM_WRITE32(RIO_P0RIWAR1, 0x8014400f); // all the write should go through O2M1

MEM_WRITE32(RIO_P0RIWTAR1, (DST_ADDR >> SHIFT12));

//MEM_WRITE32(RIO_P0RIWBAR1, (2<<20)|(DST_ADDR >> SHIFT12));

MEM_WRITE32(RIO_P0RIWBAR1, (DST_ADDR >> SHIFT12));

#ifdef LATE_ARBITRATION

MEM_WRITE32(GCR_GCR12, 0x000100ff); // weighted/late arbitration in RIO

#endif

//---------------------------------

// Configure O2M

MEM_WRITE32(RIO0_O2MCR, 0x01050000); // max burst size 64B

// Configure OCNDMA Address Translation Management Unit

MEM_WRITE32(RIO0_D2O_LAWBAR0, SRC_ADDR >> SHIFT12);

MEM_WRITE32(RIO0_D2O_LAWAR0, 0x80b0000f); // OCN to MBus Bridge 0

MEM_WRITE32(RIO0_D2O_LAWBAR1, (1<<20)|(DST_ADDR >> SHIFT12)); //+1

MEM_WRITE32(RIO0_D2O_LAWAR1, 0x80c0000f); // RapidIO Delta Port 0

Hi David,

can you help me with this questions so I can help you with this issue please:

Which software are you using?
What do you mean that it is not working as expected?
What exactly are you doing? What do you mean that the DST address cannot

receive any data?

4. Which version of the SDOS tools are you using?

Any more information can be greatly appreciated.
