sd card mounting issue #47

Open laurentvm opened 6 years ago

laurentvm commented 6 years ago

With brand new freematics, there is some software installed on those. When you run it, there are sometimes issue when mounting the card:

--- Miniterm on COM7  115200,8,N,1 ---
--- Quit: Ctrl+C | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H ---
ESP32 240MHz 4MB Flash
Power-saving disabled
MEMS...9-DOF OK
ACC BIAS...-0.06/-0.00/-1.00
SD Card:15732MB
OBD...

Works ok. You relaunch again, no card found.

Would it be possible to get the code running on new devices? Why is it failing while the card is still in.

This issue is still alive. Stanley would you have an idea.

stanleyhuangyc commented 6 years ago

How did you "relaunch"?

laurentvm commented 6 years ago

Unplug usb and replug usb.

I am having a similar, perhaps identical issue with the current version:

ESP32 240MHz 4MB Flash
MEMS...OK
ACC Bias:0.00/-0.23/0.77
SD...[E][sd_diskio.cpp:739] sdcard_mount(): f_mount failed 0x(3)

I can understand FS corruption when the firmware crashes. However, this happens also when I flash a new firmware: upon restart, I get this error. I have to remove the card, reformat and restart yet again.

In my case there is a workaround at least. @lalten do you still have this issue? How did you solve it? @stanleyhuangyc is there a way to powercycle the SD reader from within a sketch without physically unplugging the whole unit or the card? My understanding of the schematics says "nope".

I think my SD card had a gpt on it instead of msdos partition table. not sure what I changed in the end, sorry...

I guess I'll have to implement the workaround, I'm being hit by this issue about half the times I flash a new firmware, quite annoying.

In the meantime, I'll create its own bug report with different description
