WEBENCH® Tools/MSP430F5529: Difference between 2 silicon version

Maybe it is not related to silicon, but to factory preloaded USB BSL version. Try to replace BSL on rev K, with older one from revision F.

Dear Team,

We've looked it up on the errata at http://www.ti.com/lit/er/slaz314w/slaz314w.pdf

and it seems like the BLS7 can't work with revision K of the silicon.

Can you advise why this change has been implementable ?

Can you also advise any method of running the BSL the customer uses with older revisions on the new silicon without upgrading this ?

Best regards,

Nir.

Hello,

I investigated the problem.

Revision K can work with the old BSL. 

The only difference I can see in this project:

During the product's ATP the MSP is reset using pin 76 (global reset). 

With rev. F, the reset works. But not with rev. K. 

In F, K I completely erased the BSL. Then I ran a simple program that sets a GPIO pin to '1'

With rev. F, the reset set the GPIO to '0'. 

With rev. K, the reset did not change the GPIO. 

Thank you,

Zvika 

Hello,

Attached a code I compiled with CCS 4.1.2

It sets a GPIO to '0' which turns on a LED.

In my scenario, the RESET signal applied is not a pulse. 

I set the RESET to '0' for a very long time (e.g 10 seconds).

In the 'F' revision, applying RESET turns off the LED. This is what happens when I click 'RESET' in the CCS IDE (the chip icon) 

In the  'K' revisoin the RESET does not turn off the LED. 

Thank you,

#include <msp430f5529.h>

void main(void)
{
	P1DIR |= 0xF; 						// Set P1_0,P1_1,P1_2,P1_3 direction to out (LED)  
	P1OUT |= 0xF;						// Turn off P1_0,P1_1,P1_2,P1_3
	
  	//Turn on P1_4	
	P1OUT &= 0x7;
            
	while (1);
}

Hello,

I installed the MSP430 (Rev K) on the evaluation board and ran the code.

The code turns on the LED on the EVB. 

Then I disconnected the JTAG connector and pressed the RED reset button.

The LED did not turn off.

Is this the scenario you tried  ?

Thank you,

Hello Zvika,

As stated before I tested this on the MSP430F5529 Launchpad which has Rev K on it. I have also tried it wiht the MSO-TS430PN80USB Target board and do not see the issue. Please know, that I tested the target board by pulling power to the board as the board does not have a RESET button. It does have one button, S3, that is red, but it is not a Reset button. This button is used to pull the PUR line high when powering the device in order to invoke the USB BSL.
