@P-R-O-C-H-Y What kind of SD card do you have? Does it have UHS markings on the card or is it just a SDHC/SDXC card? (or even just SD, which is...
Can you try to format it using some SD-format tool? Or format it using some non-PC device like a camera. It might be the partitioning is unconventional and/or the file...
Maybe also try some SDHC/SDXC card? Those UHS cards may want to negotiate a lower signal level of 1V8. Not sure if this is expected or required. I know it...
I'm not sure if SDHC uses DDR signalling. If I'm not mistaken, this was initially only a protocol update to support cards > 2 GB. There is a "high speed"...
Hmm I took another look at the source code of this PR and ```c++ host.flags &= ~SDMMC_HOST_FLAG_DDR; ``` looks like it is disabling DDR? If so then I am quite...
Hmm these defines for sure would be a lot more clear with quite a bit more comments... https://github.com/espressif/esp-idf/blob/8f1e7bc4e08878f5a2aab55fdf302789d3a3eac4/components/sdmmc/include/sd_protocol_types.h#L198-L205 ```c++ #define SDMMC_FREQ_DEFAULT 20000 /*!< SD/MMC Default speed (limited by clock divider)...

Which (example) code do you use?
You need to divide the HDOP by 100.0f I also use altitude.meters(), but this does return a `double` So you might want to try `altitude.value()/100.0f` so you get the value...
