Kinetis processorexpert code generation bug2?

BenFan — Thu, 19 Sep 2013 20:14:07 GMT

I discovered a difference in code generation for processorexpert SynchroMaster (SPI) component when I use 2 cpu clock configurations.

It's in function SendChar.

One cpu clock configuration OK:

byte SPIFLASH_SendChar(SPIFLASH_TComData Chr)

{

SPIFLASH_TComData TmpChr = OutBuffer; /* Save OutBuffer value */

if ((SerFlag & FULL_TX) != 0U) { /* Is last character send? */

return ERR_TXFULL; /* If no then return error */

}

if (EnUser) { /* Is device enabled? */

SMasterLdd1_Main(SMasterLdd1_DeviceDataPtr);

OutBuffer = Chr; /* Save character */

if (SMasterLdd1_SendBlock(SMasterLdd1_DeviceDataPtr, (LDD_TData *)&OutBuffer, 1U) == ERR_BUSY) { /* Send one data byte */

OutBuffer = TmpChr; /* If is device busy, restore OutBuffer value */

return ERR_TXFULL;

}

SMasterLdd1_Main(SMasterLdd1_DeviceDataPtr);

} else {

OutBuffer = Chr; /* Save character */

SerFlag |= FULL_TX; /* ...and set flag */

}

return ERR_OK;

}

Two cpu clock configurations ERROR

byte SPIFLASH_SendChar(SPIFLASH_TComData Chr)

{

if (!EnMode) { /* Is the device disabled in the actual speed CPU mode? */

return ERR_SPEED; /* If yes then error */

}

SPIFLASH_TComData TmpChr = OutBuffer; /* Save OutBuffer value */

SMasterLdd1_Main(SMasterLdd1_DeviceDataPtr);

OutBuffer = Chr; /* Save character */

if (SMasterLdd1_SendBlock(SMasterLdd1_DeviceDataPtr, (LDD_TData *)&OutBuffer, 1U) == ERR_BUSY) { /* Send one data byte */

OutBuffer = TmpChr; /* If is device busy, restore OutBuffer value */

return ERR_TXFULL;

}

SerFlag &= (byte)~(TX_BUF_EMPTY); /* Clear TX_BUF_EMPTY flag */

SMasterLdd1_Main(SMasterLdd1_DeviceDataPtr);

return ERR_OK;

}

I have tested this with few test projects and different toolchains in CW 10.4.

Any suggestions what should I try to get this solved?

thnx,b

Hello,

I have reproduce it and I have classified it as bug in CW V10.4. The fix of this issue will be published in CW V10.6 (Q1-Q2 2014). For now as workaround is necessary to freeze generated code of this component. This feature is available after right click on the component, command Code Generation -> "Don´t Write ...."

Note: For future issue related to the Processor Expert please use corresponding forum: https://community.freescale.com/community/pex

In case the workaround would not be sufficient for you we will prepare hot-fix for this issue.

We are sorry for inconvenience.

Best regards

Hello,

I have just find out that issue was already fixed in CW V10.5.

Could you please to move to this version or you would like rather prefer hot-fix for CW V10.4?

Best regards

Screwed again. Seems like every time I find out the last 3 days were wasted because of a "bug" that is resolved by a CW version update, it costs our company $1600 to get the license file updated.
