Forum Post: Porting UART/I2C/SPI from BIOS5 to SYS-BIOS6

Hi,

I am porting UART/I2C/SPI modules from DSP-BIOS5 (PSP 1.30.01) to SYS-BIOS6 (BIOS PSP 03.00.01.00).

I have updated followings

BIOS5

***********

GIO_Attrs           gioAttrs            = GIO_ATTRS;

chanParams.hEdma = hEdma[0];

Int32 status;

/* create SPI channel for transmission */

 spiflashHandle =  GIO_create("/SPI1",IOM_INPUT,&status,&chanParams,&gioAttrs);

*******************

to

SYS-BIOS56

$$$$$$$$$$$

GIO_Params gioParams;

Error_Block eb;

Error_init(&eb);

Spi_ChanParams      chanParams;

chanParams.hEdma = hEdma[0];

gioParams.chanParams = &chanParams;

/* create SPI channel for transmission */

spiflashHandle =  GIO_create("/SPI1",GIO_INPUT, &gioParams, &eb);

$$$$$$$$$$$

This compiles and links fine. But below modifications BIOS5 (.tcf) to SYS-BIOS6 (.cfg) gives following error while loading/running file.

&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&

ti.sysbios.io.DEV: line 94: mdBindDev failed

xdc.runtime.Error.raise: terminating execution

&&&&&&&&&&&&&&&&&&&&&&&&&&&&

BIOS5 (.tcf file)

********************************

bios.UDEV.create("UART0");

bios.UDEV.instance("UART0").initFxn = prog.extern("UartInit");

bios.UDEV.instance("UART0").fxnTable = prog.extern("Uart_IOMFXNS");

bios.UDEV.instance("UART0").fxnTableType = "IOM_Fxns";

bios.UDEV.instance("UART0").deviceId = 1;

bios.UDEV.instance("UART0").params = prog.extern("uartParams");

*********************************

to

SYS-BIOS56(.cfg file)

$$$$$$$$$$$

var iomFxns = "Uart_IOMFXNS";

var initFxn = "UartInit";

var deviceParams = "uartParams";

var deviceId = 1;

GIO.addDeviceMeta("/UART0", iomFxns, initFxn, deviceId, deviceParams);

$$$$$$$$$$$

What is wrong here ?

Thanks
