MSP430F5635: change BSL from given examples is not working (not clear)

Andreas Haas said:

I'm using an MSP430f5635  and I want to use the BSL via USB.

I have to made some changes because my XT2 Crytall Frequenzy is on 16 MHz. 

So 1. Question : Which source File do I have to  use for changing Frequenzies and other device informations (& what other informations do I have to change or to replace )

You can do it without rebuilding. Extract BSL binary from your device, find and change USBPLLDIV value from 3 to 2, for 12 MHz. And write it back.

hi thanks for replying.
ok sounds clear but wich given source file do i have to use for changing the clk values.
because there is not the one custom BSL 430 project. The usb one is for the msp430f552x. Is it working for every msp430 ??

You have to modify the F552x USB project for your own MSP4305635 device if you plan on doing a complete re-build. The USB peripheral remains the same but the linker files (for memory organization) are swapped. Or as zrno suggested, you could read the BSL binary, overwrite the USBPLLDIVB register located at 912h, and re-program your device.

Ryan

ok ok :) wich linker file do i have to use or do i have to modify the existing one ? or is there one for f5635 ?

how can i readout the flash of the msp ? i am using elpotronic fet pro430 but when i readout it starts on @1000 how should i change or readout the values below 1000 to get the 912 ?

There is USBPLLDIVB calculation for XT2 inside PI_init() from BSL430_USB_PI.c file, and later calculated value is applayed inside USB_enable() from usb.c file.

As I allready written, for me easyest way will be to modify extracted binary (TI txt file) from original device.

void PI_init()
{
...
  unsigned int timerCCR = TIMER_CCR; // Using local variable to compare register
  if( timerCCR > (((SPEED_1 + SPEED_2) / 2)/ ACLK_DIV_SPEED) )
  {
    wUSBPLL = *(&cSPEED_1_PLL);           // Referencing a constant is done in order to force
                                          // the compiler to place the constants in flash
                                          // and use them to initialize the PLL.  This way
                                          // the constants can be modified in the binary image
                                          // in order to change the desired crystal frequency.
                                          // for instance: all values to 20MHz
  }
  else if( timerCCR > (((SPEED_2 + SPEED_3) / 2)/ ACLK_DIV_SPEED) )
  {
    wUSBPLL = *(&cSPEED_2_PLL);
  }
  else if( timerCCR > (((SPEED_3 + SPEED_4) / 2)/ ACLK_DIV_SPEED) )
  {
    wUSBPLL = *(&cSPEED_3_PLL);
  }
  else
  {
    wUSBPLL = *(&cSPEED_4_PLL);
  }
...
    USB_enable();
    USB_reset();
    USBCNF |= PUR_EN; // generate rising edge on DP -> the host enumerates our device as full speed device
  }
}

VOID USB_enable()
{
    volatile unsigned int i;
    volatile unsigned int j = 0;

    USBKEYPID   =    0x9628;            // set KEY and PID to 0x9628 -> access to configuration registers enabled
    
    USBPLLDIVB = wUSBPLL;              	// Settings desired frequency
    USBPLLCTL  = UPFDEN + UPLLEN;       // Enable PLL, Phase Freq. Discriminator enable
    
    //Wait some time till PLL is settled
    do {
        USBPLLIR    =     0x0000;       // make sure no interrupts can occur on PLL-module
        
        __delay_cycles(1001);           // For lowest code size use a cycle count that is 3*n + 2
                                        // where n is any integer greater than 4 (IAR uses other
                                        // instructions when n is less than 5).
        if (j++ > 1000)
            return ;
    }while (USBPLLIR != 0);
	USBCNF |= USB_EN;                   // enable USB module    
}

Change the device derivative inside of the Project Properties and it will change linker files automatically, there is one pre-designed for the F5635. And you misunderstand me, you need to find where in the binary image the 0912h address is written to and change that value accordingly. Perhaps zrno can help detail this process.

Ryan

thank you guys for helping me throug this :)

@zrno ok i read out the bsl memory and it looks like this :

where and what to change now ?

regards, Andi

Hi again :)
I'm still fighting with this problem.

What i did so far : 1) i took the custom Project & changed in the device.h file the clk things to 16 000000
and changed XT2 PORTSEL to 7. The project options in IAR are changed to MSP430f5635 and the linker file setting is choosen to overwrite original and the linker file is the : lnk430_BSL_AREA_RAM_2400-33FF.

2) I took my user application and checked with debugging that the

__disable_interrupt(); // Deaktivieren des Global-Interrupts, um Bsl nicht zu st�ren
((void (*)())0x1000)(); // Aktivieren des Bsl

part is entered. Then i took the output. txt files from both applications and put them together like mentioned in SLAA452 -> 6.1.
Then I took the txt file and flased it on my device.
When entering the bsl mode my device manager from windows should recognise a USB device with PID 0x0200 & VID 0x2047 but nothing happens.
Am i missing something out ??

Do I have to change something else somewhere ??

Thank you
regards,
Andi

Hi zrno

thanks for your reply :) 

I read out the BSL of a new MSP430f5635 and i changed the hex numbers you told me. for 16Mhz it is 11 04. 

Then i pulled the PUR pin up while i started the device. 

Device manager in windows shows : unknown device, I don't get a VID & PID. 

do have any ideas what is still wrong ?

Thank you

regards 

Andi
