CCS/MSP430FR6989: CCS/MSP430FR6989:

Dear Katie
Thanks for the detailed replay and sorry on the delay in mine response.
My goal is to create a similar device to the msp430 REP in order to flash msp430g2553 mcu without pc host.
I was uder the impression that the jtag interface is more ideal for this purpose but since i have no need in debugging the mcu, i will try out your suggestion and check the BSL interface option.
I will probebly seek for guidance soon : )
Best regards,
Avraham

Hi Katie

I have recently ordered and received msp430f5529 lp.
I assumed that it woulde be esaier to adjust the msp430 replicator code (from slau320y.zip) to it and use it as host for flashing the msp430g2553 (as i have posted before).
And yet i'm struggling a lot to do so.
I'm using CCS V6.2 and the replicator430 (for original MSP430 architecture devises) code.
I intend to use SBW connections between host (msp430f5529lp) and the target (msp430g2553).
The current situation is that the program gets trapped at the the InitController(void) function at the

loop --->// Loop until XT1,XT2 & DCO stabilizes

//! \brief Initialization of the Controller Board
void InitController(void)
{
// Stop watchdog timer to prevent time out reset
WDTCTL = WDTPW + WDTHOLD;

// Set higher Vcoree, to be able to handle the MCLK freq = 18 MHz
SetVCoreUp( 2 );

//****** set XT1 clock - crystal 12 MHz **********

// P7SEL = 3; // Port select XT1
P5SEL |= BIT4+BIT5; // Port select XT1
UCSCTL5 = 0; // DIVPA, DIVA, DIVS, DIVM -> all direct (DIV=1)
UCSCTL6 = XT2OFF+XT1DRIVE_1+XTS;
// XT2 OFF, XT1-ON
// Drive strength - 8-16MHz LFXT1 HF mode


// Loop until XT1,XT2 & DCO stabilizes
do{
// Clear XT2,XT1,DCO fault flags
UCSCTL7 &= ~(XT2OFFG + XT1LFOFFG + XT1HFOFFG + DCOFFG);
// Clear fault flags
SFRIFG1 &= ~OFIFG;
}while( SFRIFG1 & OFIFG );



// Select ACLK = LFXT1 = 12MHz
// SMCLK = LFXT1 = 12MHz
// MCLK = LFXT1 = 12MHz
UCSCTL4 = SELA_0+SELS_0+SELM_0;

#ifdef MCLK_18MHZ
// DCO-freq range up to min 39MHz (must be higher then 18MHz*2 = 36 MHz)
UCSCTL1 = 6*DCORSEL0_L;
// DCO-DIV/2, PLL MULTI*(23+1), freq = 24*0.75 = 18 MHz
UCSCTL2 = FLLD0 + 23*FLLN0;
// Reference - XT1-CLK, XT1/16 = 0.75MHz
UCSCTL3 = FLLREFDIV_5;
// Loop until XT1,XT2 & DCO stabilizes
do{
// Clear XT2,XT1,DCO fault flags
UCSCTL7 &= ~(XT2OFFG + XT1LFOFFG + XT1HFOFFG + DCOFFG);
// Clear fault flags
SFRIFG1 &= ~OFIFG;
}while( SFRIFG1 & OFIFG );

UCSCTL4 = SELA__XT1CLK + SELS__DCOCLKDIV + SELM__DCOCLKDIV;
#endif

// Setup timer_A for hardware delay
TA0CTL = 0; // STOP Timer
TA0CTL = ID_3+TASSEL_1; // Timer_A source: ACLK/8 = 1.5 MHz
TA0CCR0 = ONEMS; // Load CCR0 with delay... (1ms delay)

//****** clock setup is done **********

#if(0) // can be enabled for test /debug
// SMCLK (18 or 12 MHz) freq test on the S1 switch (open) - test time ~ 10ms
P1SEL = 0x40; // SMCLK - to P1.6 (S1 - button)
P1DIR = 0x40; // for clk test only - must be disabled later
MsDelay( 5 );

P1SEL = 0;
// END OF SMCLK freq test on the S1 switch
#endif

TRSLDIR = 0;
// set port to output from MSPF5437 to I/O translators
TRSL_CDIR = TEST_DIR + RST_DIR + TCK_DIR + TMS_DIR + TDOI_DIR + TDI_DIR;
// set all directions from I/O translators to MSP430F5437
// (all I/O JTAG lines to input)
TRSLDIR = TEST_DIR + RST_DIR + TCK_DIR + TMS_DIR + TDOI_DIR + TDI_DIR;

// set LED ports direction
LED_DIR |= LED_YELLOW+LED_GREEN+LED_RED;
// TURN-ON all LEDs at the startup
LED_OUT |= LED_YELLOW+LED_GREEN+LED_RED;

// set SW ports pull-ups
SW_PULLUP |= SW_MODE0+SW_MODE1+SW_1; // set pull-up/pull-down
SW_OUT |= SW_MODE0+SW_MODE1+SW_1; // select pull-up

SetTargetVcc (0);
SetVpp( 0 );
}



i have configured the XT1 crystal to the msp430f5529 lp
// P7SEL = 3; // Port select XT1
P5SEL |= BIT4+BIT5; // Port select XT1

I hope we will find a way to implement this program in to this mcu (msp430f5529) since it's highly importent for our App.

thanks in advance
Avraham

HI Katie

Thanks alot for your quick and detailed response i very grateful for it.
I will try to change the code (according to your advices) and i will get in to it right away.
I just want to confirm with you one more thing.
Is my assumption regarding to the implementation of the Replicator code to the msp420lp correct?
Because i cant find any reason why not .
I will update soon...
Thank again,

Avraham

my assumption is regarding to the implementation of the Replicator code to the msp430f5529 lp (not msp420lp)...

hi

i just want to currect katie`s comment:  On Msp430F5529  - XT1 - DOES NOT support high frequency crystal,  ONLY XT2

thanks

avi

Hi Avi,

Thanks for the correction. I was thinking generally of F5xx/6xx family devices, some of which can support high frequency crystal on XT1, but you are correct now that I check F5529 datasheet specifically only supports low frequency on XT1. I will update my original post so it is more clear for people reading this thread.

Regards,

Katie

Hi Avraham,

I'm not sure which assumption you are referring to. Are you asking if it is easier to port the Replicator code to the MSP-EXP430F5529LP than to the MSP-EXP430FR6989? It will probably be easier since the code was originally written for the MSP430F5437 device which is in the same family as MSP430F5529, so they have similar clock system, PMM modules, etc. However, you will still have to make some clock initialization changes as you have found, and likely some changes of what port pins are used etc.

Katie

Katie,

is there any similar code as the replicator but only for 2 wire (SBW) only, more simple code. we also would like to use a host controller as a programmer of multiple msp430g2553 devices.

it would be great if u fimiliar with that . our future host MCU will be MSP430F5659 / or similar

our project will require a large qty`s of your products.

thanks
avi

Hi Avi,

As I mentioned earlier in my first post, the replicator SBW code itself (even if it was just implementing SBW) is quite complicated because it is muxing 3 JTAG signals onto a single bi-directional communication line via time-division multiplexing - it gets very time sensitive and it is essentially bit-banging the signals. I would strongly recommend bootloader BSL as a preferable programming solution instead, because it is very simply a list of commands implemented on top of a basic 9600 baud UART interface. There is more information about the MSP430G2553 BSL found in the BSL User's Guide www.ti.com/.../slau319 and that should include all of the information you would need to create a host interface for G2553. You just have to generate the entry sequence, and then the rest is all commands over UART as described in the document.

Regards,
Katie

Also, are you aware of the MSP-GANG programmer tool which can program up to 8 MSP430s stand-alone (doesn't have to be connected to PC)? If you simply need a production programming solution, perhaps this would be better supported than having to create your own.

HI Katie

I read the slau319 and other guides (including the threds in the e2e support) as well and i have a few questions in order to complete our costum programmer project for the msp430g2553 .
In order to program the msp430g2553 MCU via BSL, as i uderstood, i can only use custum BSL methode.
First i need to program the target with the BSL commands in to its flash memory (since i cant invok the BSL in MSP430G2553 ROM) , than to Invoked it externally (from the host) by the correct BSL sequence and than program my desired code to the available flash memory (alongside with the BSL commands for the next programming)?
Am i the first one to creat such a project or is there anything similar to it that i can costumize somehow to our goals?

Thanks for all the attention,
Best regards,
Avraham

Hi Avraham,

You should not have to create a custom bootloader for the G2 device, you will only have to create the host software that talks to the ROM BSL that is already built-in to the device. You should be able to invoke the built-in ROM BSL on the MSP430G2553 if you use the correct sequence on TEST and RST pins. This sequence is described in the BSL user's guide www.ti.com/.../slau319 section 1.3 Standard RESET and BSL Entry Sequence. See the device datasheet www.ti.com/.../msp430g2553 section titled "Bootstrap Loader (BSL)" which explains which pins are used for BSL TX and RX on this device. The BSL user's guide SLAU319 explains in chapter 2 the protocol that you should follow for the G2xx device to implement a BSL host.

There is PC software existing called BSLDEMO that is included in the BSL Scripter download (see the MSPBSL page) that includes source code. But that is written to run on a PC so it may not be the easiest to adapt. There is also included in the BSL Scripter Download, in the Deprecated folder once you unzip it, BSL Replicator code including documentation and source code.

Regards,
Katie

Katie,

why there is no simple code example for bsl / uart that can simplified that - host controller and target controller flashing code.

i am sure it was made in the past many times.

please let me know if there is any.

thanks!

Hi Avi,

Please see the BSL Replicator included in the BSL Scripter download I mentioned in the post above - it really is only 1 c file so very simple. Additionally, I believe that someone from TI may have been working with your company off of the forum as well to provide you a more full-featured example already ported for the particular host controller you are using - can you check?

Regards,
Katie
