Now if i put the correct firmware i see always this message:

[Flash Download]
Fail!!(Download) BROM_CMD_START_FAIL
[Finish]
Take(6) secs to test.

I try with the vcc trick but dont works.
I try with flash tool 1.0.0 but dont works.

SOLVED :slight_smile:

I try to solder VCC directly to the GPS and with VCC trick reflash started yuppiiiiiiiii :slight_smile:

But works only with MTK_AllInOne_DA_MT3339_E3 download agent and AXN2.10_5122_3339_384.1151100.1 firmware with the AXN1.51_2722_3329_384.1151100.5 dont works.

Dont have any chance to put the AXN1.51? Because i have MT3339 not 3329 i think.

Hi, I have exactly the same problem.
I flashed my Pa6C with LLC with AXN2.10_5129_3339_1152.1151100.10.bin and it still seems to live, but doesn’t give valid NMEA output in any of the baudrates and is not flashable any more.
I couldn’t find anything about the VCC trick. Can you please explain?
Currently, I’m driving the module with VCC from USB.

Alive again :wink:

I set the update baudrate to 9600bps, prepared everything, clicked “Download” and powered on the GPS shortly AFTER clicking. That did the trick. Upload worked fine and it is alive again!

Hi,

reading eosbandi code we can see :

#if defined(MTK_BINARY16)
            GPS_read[LAT]		= _buffer.msg.latitude * 10;	// XXX doc says *10e7 but device says otherwise
            GPS_read[LON]		= _buffer.msg.longitude * 10;	// XXX doc says *10e7 but device says otherwise
#endif
#if defined(MTK_BINARY19)
            GPS_read[LAT]		= _buffer.msg.latitude;	// XXX doc says *10e7 but device says otherwise
            GPS_read[LON]		= _buffer.msg.longitude;	// XXX doc says *10e7 but device says otherwise
#endif

Only AXN1.51_2776_3329_384.1151100.5_v19.bin firmware can have real 10e7 pecision.
On google group I have fond this thread :

groups.google.com/forum/?hl=it& … XQ74d5x1sJ

we can use this firmware ?

Thanks

I think this firmare is for MT3329 GPS. I have never used it.

13

how do you solder it directly to the GPS…is it from FTDI vcc to the vcc GPS directly solder?

Hi…i am a new user here. I think you should update baudrate to 9600bps and prepare everything, click Download and give power to the GPS shortly AFTER clicking. Upload it and it ll work fine.
