MSP430F5501: MSP430 jumping out of BSL mode

Go Vin
Intellectual 330 points
Part Number: MSP430F5501


I use MSP430F5501 for many years. We built new batch of boards this month. After programming MSP430, it executes program. On previous boards, the command to jump to BSL works perfectly but in this new batch it cannot stay in BSL mode. I see USB is disconnect after sending jump to BSL command but it cannot stay in BSL mode and enumerates again. It is running my program again. Through my program debug interface i check JTAG and BSL lock. It is set to jump to 0xFFFF and 0x1000 respectively. I have no communication problem and the board has no other external connection during this test.

After much debug and not finding a cause, i thought i will check on this forum. Is there any change in MSP430F5501 that can result in such issue? Is there any external condition that can cause MSP430 not to stay in BSL mode? RST pin is pulled up to Vcc with 47K and 2.2nF connected to ground.

Please help!

    Hi Go

    You use the software invoke of set the PC to 0x1000 in the program, right?

    How do you download the application code ? JTAG or BSL?

    How about a use a blank device to use the BSL?

    Hello Gary,

    Yes,i use the software invoke of set PC to 0x1000 in my program.

    I downloaded the application code through USB with MSP430 in BSL mode. 

    I successfully programmed few blank device through USB/BSL but none can return to BSL in the latest batch. Same program can return to BSL in previous batches. Gerber and placement are identical.

    My thoughts: Blank device can be programmed mean that there is soldering or component problem. This indicate that there may be change in MSP430F5501. One more doubt: In this batch vendor used package MSP430F5501IRGZT. Previous batch used MSP430F5501IRGZR which is not in stock. Vendor said both are identical and I did not spot any difference.

    Best wishes

    Hello Gary, I compared Hardware and firmware revision of old and new batch of MSP430F5501 by reading memory contents

    Old is 0x12, 0x12

    New is 0x15, 0x14

    Hi Go

    What's the supply voltage do you used in VCC?

    Hi Gary,

    Vcc is 3.3V from VUSB. I used recommended 220nF capacitor. Worst case external load for Vcc in my application is 1.5mA peak pulse. I disconnected external load for test.

    Thank you

    Hi Go

    Have you try the BSL hardware invoke(pull up the PUR pin when power up) with the problemed device?

    Dose the problemed device failed every time when use the software invoke?

    Hello Gary,

    I tried with PUR pin pull up to external 3.3V Vcc. It still fail to enter BSL. 

    Is there a known condition that cause software invoke of BSL to end with reset? MPS430 is disconnected from USB with software invoke of BSL but cannot stay in BSL mode.

    Best wishes,

    Go

    Hi Go

    What's the device versions of the old and new? Are they both Rev F? We have four version of devices before C, D, E and F. The F is latest version.

    Your problem can summary like this:

    When device is blank,  there is no problem. But when you download your application code, the BSL can't work both hardware invoke or software invoke with any device any time, right?

    Hello Gary,

    Your problem summary is right.

    How do i get device version? I read TLV record Hardware and firmware revision of old and new batch of MSP430F5501 by reading memory contents

    Old is 0x12, 0x12

    New is 0x15, 0x14

    Can you find device version from this information?

    The device version is on the top of the device. I can see it.

    Can you download other demo code from TI like GPIO toggle project to see if BSL works?

    Hello Gary,

    Top marking on old devices: M430 F5501 TI 16K C DTDV G4 and M430 F5501 12K C C6EE G4

    Top marking on new device: M430 F5501 TI 73K F DC98 G4

    I will try download other demo project later today.

    Hello Gary,

    I programmed demo code and it cannot return to ROM with command that execute call to BSL.

    If i lock BSL 0x17FE/FF = 0x1000, then it cannot return to ROM even if i connect PUR to VUSB.

    If i do not lock BSL, then it can return to ROM only if i connect PUR to VUSB.

    I damaged many boards now. How can i make call to BSL work? I disabled all interrupt before call BSL. I read that NMI could cause problem. Do you have suggestion?

    In version C call to BSL works correctly. This problem is only in version F.

    Hi Go

    Sorry for the late response

    Please try to reset the USB module before you jump from software to BSL

    // configuration of USB module
    USBKEYPID = 0x9628; // set KEY and PID to 0x9628 -> access to configuration registers enabled

     USBPWRCTL = 0; // Workaround for USB9
     __no_operation(); // for workaround USB9
    USBPWRCTL = VUSBEN + SLDOEN + SLDOAON /*+ VBOFFIE + VBONIE*/; // keep primary and secondary LDO (3.3 and 1.8 V) enabled

    Have you locked the JTAG? If not, could you read out the data from 0x1000 to 0x17FF?

    Hello Gary,

    I don't get easy access to JTAG on my board. But i read BSL area from my test program. I attach data 0x1000-0x17FF

    Hi

    That seems you have locked JTAG. Could you have a try to power the VCC by external 3V3?

    Hello Gary,

    Could JTAG lock affect jump to BSL? I erased last row of program from my running program and when i reconnect USB it started in BSL even though JTAG lock.

    Kindly let me know if it is safe to connect external Vcc continuously when i have MSP430 output Vcc on. Otherwise I have to cut PCB trace.

    Best
