MSP430F2370: Porting code

Hi Xiaodong,

The customer has modified the register and the corresponding port. Then the dco calibration value is erased. Do you know the CALBC1_8MHZ value corresponding to msp430f2370? In addition, the code he ported is TRF7970ABP_RFID_Reader_Demo

In addition, after the customer ported the TRF7970ABP_RFID_Reader_Demo code to the msp430f2370, the program got stuck in the vlo startup file. May I ask why?

Regards,

Annie

Hi Annie

>>  Then the dco calibration value is erased. Do you know the CALBC1_8MHZ value corresponding to msp430f2370?

Please check 24.1 TLV Introduction of MSP430F2xx, MSP430G2xx Family User's Guide (Rev. K)

DCO Calibration TLV address should be the same between F2 and G2 device. Please check if all the TLV data are erased.

>> In addition, after the customer ported the TRF7970ABP_RFID_Reader_Demo code to the msp430f2370, the program got stuck in the vlo startup file. May I ask why?

Please check the VLO calibrary application notes on: https://www.ti.com/lit/ml/slaa340a/slaa340a.pdf

Hope customer can debug this issue based on this documentation.

or customer can consider temporarily remove this function for debug.

Thanks!

How is the symbol "TACCTLX" defined? This would be the timer CCI channel (usually CCIxB) which is connected to ACLK.

For the G2553 this is CCI0B (TACCTL0) [Ref data sheet (SLAS735J) Table 12]. For the F2370 this would be CCI2B (TACCTL2) [Ref data sheet (SLAS518E) Table 14]. If there's a TACCRX defined you probably have to change that too.

-----

The CALDCO constants are different for every chip, so you can't "transplant" them. If you have a precision timing source (typically a 32kHz crystal) on your board, you can re-compute the constants using the msp430x23x0_dco_flashcal.c example here:

Hi Xiaodong,

Hi Annie

Could you please explain your question on this source code?

Thanks

Hi Annie
Please check the description of BCSCTL1 and DCOCTL register on MSP430F2xx, MSP430G2xx Family User's Guide (Rev. K)

Hi Xiaodong,

The picture above is the DCO constant corresponding to a msp430f2370 chip detected by the customer.

Now, after he ported the code sloc297 to msp430f2370, the nfc tag could not be recognized and read. He would like to know how to resolve it?

Thanks,

Annie
