Following the following procedure can upgrade the firmware to R71
- start the DWLWin v22.214.171.124.exe(from wavecom website), and press the connect(note: the fastrack is powered off).
- ground the boot pin with 10k resistor(the manual said connect to 1.8v, but I tried and doesn’t help, I get this information from another thread in this forum).
- connected the fastrack to the power.
then the fastrack supreme will enter the bootloader mode and connect to the DWL Win.
then you can download the R7.1a_01-cus-q26-01.wpk(you can get it from the wavecom website) to the fastrack supreme. then the firmware is upgraded.
Ground the boot pin(a tricky job) will make the fastrack supreme enter the bootloader mode when powered on(only in this mode can talk to DWL Win), but it only stay in this mode for a very short time, someone said just 1 or 2 second, it’s why we need to get everything in the DWL Win ready before powered on(1.selcet the upgrading file *.wpk, only this file is necessary. 2 press start or connect(I can’t remember exactly but you know what I mean)), so the DWL Win will keep send connect signal to the board until an connection is built when the supreme is powered on and enter the bootloader mode.
It’s sad that wavecom doesn’t document it very clear.
you will get the information about how to update the firmware with DWL Win from this document RN_Open_AT_Firmware_R7.1a_Preliminary_Customer_Release_Note.pdf
except that ground the boot pin and the exact procedure. believe me, I did it many times for Fastrack Supreme 10 thanks to helps from this forum and the distributor.
