N4 expansion board: no micro SD card works

[saihv]

Hi, I have an Autoquad M4 hooked up to an N4 expansion board, and I was trying to log flight data to a micro SD card, but any SD card operation (flight data logging, param file saving etc.) results in a FAILURE: 245 message, and nothing is stored on the SD card. I saw a couple of previous posts about this issue, which mentioned bad contact soldering etc., but the contacts on this one look good. I tried formatting the SD card as FAT and FAT32 but neither has worked. Does anybody have inputs or possible solutions for this issue?

Thanks!

Which card (maker, series) Do you use?
Autoquad requires a class 10 card!

class 10 is not needed (but preffered) i'm using class 4 Old toshiba 4GB
Make sure your SD car is ok.

I used two different class 4 microSD cards: One Sandisk and one generic. The third one I tried was a class 1 Sandisk. I have no used a class 10 because I didn't have one, but if class 10 is not mandatory, those should've worked..

My SanDisk 32GB class 10 died in a freezer

Saihv, take class 10 card but if you want to do full calibration (with freezer) choose smaller capacity (e.g. 8GB)

Thank you! I will get the 8GB Sandisk class 10 one and try it with that.
