There is the possibility to use the motorPowerSet parameter group but I think this way would be to slow to do any low level control off-board. There has been some successful attempts before like in this post but It will, if I recall correctly, require modifying firmware and writing c-code.

Are you getting different asserts or mainly the one in the usddeck.c @795: static void usdWriteData(const void *data, size_t size) { UINT bytesWritten; FRESULT status = f_write(&logFile, data, size, &bytesWritten); ASSERT(status == FR_OK); crc32Update(&crcContext, data, size); STATS_CNT_...

I would look for Hubsan x4 batteries as they fit on the CF2.1 as well. Many toy drone batteries actually does, just make sure it is the same connector and that it is thin enough to fit between the deck connectors (20mm max with). For different propellers it is probably best to change to the bigger 7...

The M1 green LED would indicate something being written to the micro-SD card, which requires a micro-SD card deck. Do you have that mounted? Are you able to enter bootloader mode and flash it with e.g. the latest stable release 2022.01? You could try connecting it to your computer using a USB cable ...

OK, good, then we know!

I don't think we have actually tried but it can very much be related to the Olimex or the configuration of it. It could be as simple as adjusting the interface setup. We have a Jlink here, I'll put a todo-note to test with this instead.

Hi Wolfgang!
This could be a reset issue of the camera. Please check this forum post. This post is also touching it. Also found a note in the jtag documentation. Let us know it that is the issue.

The power path is explained a bit in this blog post which is relevant. I think 2A per motor is not a problem but it will require to change battery as well to not trigger the PCM (short protection) in the battery. We have tested many 7x20mm motors without problem but an upgraded battery might be need...

I'm glad it works much better but I pretty sure you will hit more bugs when you stress things. Let us know if so. About your questions: 1. Yes that is correct. Fixed frequency is simpler. For events, code has to be added, but you will get each event at the right rate. 2. I think the limit is 20 vari...

Hi Dominik, I missed the fact that the fixed frequency test did not write down any log variable data. I debugged it and it turns out that our parser is not that robust and can't handle a fully commented line. So the "# IMU" in the fixed frequency test get interpreted as there are no variab...

There might be bugs still but in general the logging should work. I did some tests (#1 and #2) with 2022.01_rc1 and it worked well for me. I used a Kingston 32GB Class 10 A1 (Canvas select plus). I wonder what the difference for me is, and also why your SD-card doesn't work... sdcard-format.png sdca...
