Other Parts Discussed in Thread: MSP430FR5972

Hi my name is Luigi

sorry for my English

I would like to know if someone have problems with CPU MSP430fr5972

I'm developing a new product, I program only in Assembly and I used this CPU

but I found some problems, I would like know if there are my errors or should

be some problems on this cpu. because I need to produce I final product and want to be sure.

First of all I want to precise that I write direct data into the Information memory segment without any write

eeprom or flash mechanism like example MSP30G2553, and the data are maintained properly.

1) every time that the cpu start after reset always JUMP into the JMBINFG interrupt also when theFEt

emulator tool is disconnected.

2) The system remains stationary do not know where, if switch off the cpu and than switch on start properly

3) if with FET I set one breakpoint often don't jump into the right line but in the other line, I think this is because

id there is BIT instruction also if is NOP operation the breakpoint is lost

4) I put this electronic board near to the high temperature around 85 °C , after seome minute

the memory is erased, I don't know if all or only one part but need to program again the CPU

probably is at the temperature limit

in the case of magnetic field can should be erase thei memeory ?

other question if the memory is erase is possible through bootloader by rs232 reload the firmware

I don't have experience in bootloader.

I want to use a bootloader to upgrade the firmware there is already the utility in windows

that can be used with RS232?

best Regards

Hi Luigi,

Why are you attempting to use assembly rather than C? Modern C compilers are very efficient, and C code is MUCH easier to write and debug compared to assembly.

For the temperature testing, can you elaborate on what your heat source is, and how precise it is?

For the bootloader, please take a look at the MSP BSL Tools Page. This site provides information on all our BSL options and how to use them. Included is a document called "MSP430FR57xx, FR58xx, FR59xx, FR68xx, and FR69xx Bootloader (BSL) User's Guide". This guide would be a great starting place for learning more about the BSL on your MSP430FR5972 and how to use the bootloader.

Mike

sorry, not yet, at the moment I stopped the development about the firmware, I will finish the hardware

I will Check all in April when finish the development. .

I work in assembly from long time, I don't want to learn C because I'm not so Young

and now I develop only a few project in one year, 4 / 5 maximum, and my job is now more

versus commercial job and corporate responsability.

For the temperature testing, can you elaborate on what your heat source is, and how precise it is

About the temperature source my electronic control is use for cooking system, so I can have high temperature.

during my last test I have the system immediately on the top of the boiling water 5/5 cm over, so probably may be around 90° / 95°C into the

case where was the processor, and in this case the processor lost the firmware, after programming again work well..

you can reply to the followings my question ? step by step ?

First of all I want to precise that I write direct data into the Information memory segment without any write

eeprom or flash mechanism like example MSP30G2553, and the data are maintained properly.

1) every time that the cpu start after reset always JUMP into the JMBINFG interrupt also when theFEt

3) if with FET I set one breakpoint often don't jump into the right line but in the other line, I think this is because

id there is BIT instruction also if is NOP operation the breakpoint is lost

in the case of magnetic field can should be erase thei memeory ?

I order to the segment problems CPU40 is correct to put nop in this manner

BIT.W #BIT1 ,LABEL,JUMP

NOP

........

JUMP:

NOP

Luigi,

Do you use IAR assembler? Please show some of the code you have. I may be able to help you.

Could you show me a simple but complete example of your code. Does the cpu start after reset always JUMP into the JMBINFG interrupt?

Thank you.
I do not understand even the first line.
Are you trying to define or equate the word "BSET_W" to two words "BIT" and "W"?
My copy of IAR assembler flag your first line with "invalid syntax" or "Bad instruction".

I think I can work on your code.

(1) But please tell me which bit in P1OUT is CS_OUT?

(2) Could you send me the file used in:

I assume that one of your output pins is connected to a LED lamp.
Please edit the line "flip: XOR.B #BITx,&PyOUT" so that it will toggle the LED lamp.
Please do not change anything else and try to bedbug it.

Hi,

i solved this problem, was one error in the CLEARAMreg reg routine

but had other problem Always for one error in other soubroutine

but I see that in the

SYSTEM_VECTOR:

ADD &SYSSNIV,PC ; Add offset to jump table

RETI ; Vector 0: No interrupt

JMP DBD_ISR ; Vector 2: DBDIFG

JMP ACCTIM_ISR ; Vector 4: ACCTIMIFG

JMP RSVD1_ISR ; Vector 6: Reserved for future usage.

JMP RSVD2_ISR ; Vector 8: Reserved for future usage.

JMP RSVD3_ISR ; Vector 10: Reserved for future usage.

JMP RSVD4_ISR ; Vector 12: Reserved for future usage.

JMP ACCV_ISR ; Vector 14: ACCVIFG

JMP VMA_ISR ; Vector 16: VMAIFG

JMP JMBI_ISR ; Vector 18: JMBINIFG

JMP JMBO_ISR ; Vector 20: JMBOUTIFG

JMP SBD_ISR ; Vector 22: SBDIFG

DBD_ISR: ; Vector 2: DBDIFG

RETI ; Return

in case of VMA_ISR flag set Always the control jump to the JMBI_ISR for this reason I'm confused

I check that in the SYSTEM_VECTOR register the flag JMBI_ISR is 0 and VMA_ISR is 1 but Always jmp to the JMBI_ISR

soubroutine if is set JMBI_ISR flag or VMA_ISR

what I can solve this error ?
