I've just installed a DIMU and flashed the DIMU version of r368, but after transmitting and writing parameters to ROM, when I repower the board, the parameters haven't changed from their initial values.

Config_version = 125. I've tried setting it to 0 and rebooting, but it does the same as trying to save anything else and comes back with default params.

Anyone know where I'm going wrong?

Edit: just tried r357 and can update parameters.

Next problem... I connect using QGC, and I see the HUD spinning. Sometimes it will keep going, other times it will freeze, and the diagnostic telemtry shows 'nan' as the values for a bunch of things. All of the values that have numbers are actively changing.



I've tried the tare function. If the HUD stays active without the nan issue, then I can level successfully, but after a reboot, the HUD is back to spinning, and i get a message in the bootup log 'DIMU: cannot read EEPROM parameters!'


Edit: I've just tried pulling the DIMU off and remounting it in the socket, and it looks to be behaving for now...

I have just posted a set of default IMU params, that will make your DIMU´s act sane:

Hi,

just upgraded to DIMU and flashed the board to firmware aqv7.0.r368.b1697-hwv6.0-dimu1.1.hex (downloaded form here ftp://ftp.autoquad.org/3/334693_22529/a ... erimental/).

Problem:
When changing ANY parameter (i.e. radio type) and writing it to ROM nothing seems to be written since all parameters were on their default settings after power-cycling the board. I'm working with QGC V1.3.0 (FTDI connection to AQ6) on OS X.

So: any advice how to proceed??

Did a reset to default parameter help?

1. connect the board
2. power on
3. connect the qgc
4. open "serial console"
4. edit Radio selection
5. use store to AQ button, and select store into ROM on this dialog
6. press reset button on the fc
7. post log here.

Hi,

when talking about 'serial console' I think you're speaking of about the 'Communication Console'.

This is what I end up when doing as requested (as long as it's available in the communictaion console windows). Change radio type to Spektrum 10Bit.

Link serial port /dev/tty.SLAB_USBtoUART is connected.

I've also checked HEX but I can't see any additional data. Pls notice: this is QGC V1.3.0 on OS X 10.9.2 (might be of interest).
