Make sure the SD card is 32gb or smaller and is formatted FAT32. exFAT or NTFS will not be recognized by the PowerFlarm.

Hi All,

I have downloaded the most recent PowerFLARM firmware, filename:
pf_00cecdb_6_40_exp_1_Feb_2019.fw.Â* Per the instructions for micro SD
cards published on the FLARM website, I've attempted to update the
firmware three times as follows:

Copy the firmware file to the root level of the SD card
Insert the SD card
Apply power

My PF portable comes up quickly showing fw version 6.08.Â* There's no
30-second update time as mentioned in the instructions.Â* The
instructions say to interrupt power for at least 5 seconds after
inserting the card.Â* It seems to me that inserting the card in an
unpowered unit serves the same purpose.Â* Could that be why my unit won't
update?
