Other Parts Discussed in Thread: MSP430G2553, MSP430G2231

Hi, i'm trying to program a MSP430G2553 (that I bought) using Launchpad (MSP-EXP430G2 Rev1.4).

The connections are rigth but I'm getting this error below (at programming):

MSP430: Trouble Writing Memory Block at 0xffde on Page 0 of Length 0x4: Could not write device memory

MSP430: File Loader: Verification failed: Target failed to write 0xFFDE.

Anyone knows what is that?

Thanks

For G2553, location 0xFFDE holds the BSL-Security-Key (BSLSKEY), you normally do not write anything there unless you want to disable BSL.

Which tool chain are you using? Did you set it up correctly?

I'm using code composer, I started project using default values of CCS for it (Properties > CCS General > Main Variant = MSP430G2553)
What is "set it up correctly", specific file?

I found it at lnk_msp430g2553.cmd (CCS) and then commented out.
//BSLSIGNATURE : origin = 0xFFDE, length = 0x0002, fill = 0xFFFF
//.bslsignature : {} > BSLSIGNATURE /* BSL Signature */

But, the error now is:

MSP430: Trouble Writing Memory Block at 0xffe0 on Page 0 of Length 0x2: Could not write device memory
MSP430: File Loader: Verification failed: Target failed to write 0xFFE0

What is wrong, I just put MSP430G2553 DIP (bought from estoreti) in LAUNCHPAD socket.

I do not know how to use CCS. But I know that it shouldn't have tried to write to location 0xFFDE unless you set it up to alter the BSLSKEY. In my opinion, such an act is a fault and shouldn't be a part of default.

For G2553, location 0xFFE0 is practically useless. One seldom attempts to write there.
Are you using the "correct" header file etc.?

That's the code
-----------------------------------------
#include <msp430.h>

int main(void) {
WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer
P1DIR |= 0x01; // Set P1.0 to output direction

for(;;) {
volatile unsigned int i; // volatile to prevent optimization

P1OUT ^= 0x01; // Toggle P1.0 using exclusive-OR

i = 10000; // SW Delay
do i--;
while(i != 0);
}

return 0;
}
--------------------------------------------
And using MSP430G2553.ccxml and lnk_msp430g2553.cmd to program.

Your code definitely does not need to write anything to location 0xFFE0 (nor 0xFFDE). I have no idea why CCS tried to do that and yet cannot do it.

Could someone else that knows CCS help?

Download Fet Pro from , Selecr "FET-Pro-430 Software Pkg. - STD" and install it. On opening, erase the flash completely. It should help get back your MSP

Hi, thanks for help.

But when I tried to erase I got this.

Hello!

Please uncheck "Enable" in "Blow Fuse" section and try erasing the flash. DO NOT try to blow the fuse.

I think I got the same error.

I did this process with MSP430G2231 (Which is included at launchpad) and works.

It seems to me that it has a "factory lock", it's possible?

I'm glad you were able to resolve the issue. :) :)

No, I couldn't, the figure above is about MSP430G2231. At MSP430G2553 the problem keeps.

It is possible that this G2553 already has a "firmware" that causes its CPU to crash very quickly after power up. The crash puts the target in a state that it would not respond to even a Reset.

Most JTAG tools will power up the target without holding its nRST pin to ground. By the time when the tool tries to invoke JTAG, the target already executed is "firmware" and crashed beyond hope.

Some thing happens with BSL.

I do not know about JTAG, but I know that for BSL, this can be fixed by holding nRST pin low before the target is powered up, and start the BSL entrance sequence with nRST still being low.

Right, but how to do this at code composer. It should be easy.

I was talking about the PC program that starts BSL.

I tested code composer ate linux and works, it seems that the problem is windows driver. =(

The problem was launchpad, I changed to another board, and works. Thanks everone.
