Hi ,

I may be posting this in a wrong thread, exuses for that as i could not find the proper platform for posting this
I recently got HDK 8250 development kit and am unable to flash the device .
I built the firmware using the below steps :

1. cloned qcs8250-la-1-0_test_device.git
2. On top of this, i cloned CAF source
3. cd LINUX/android
4. source build/
5. lunch kona-userdebug
6. dist -j8  -> Build HLOS images
7. cd ../../common/build
8. python -> Build Non HLOS images

Finally, when its time to flash,  fastboot doesn't detect my device

This is my 51-android.rules
SUBSYSTEMS=="usb", ATTRS{idVendor}=="18d1", MODE="0666", OWNER="plugdev"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="05C6", MODE="0666", OWNER="plugdev"

lsusb detects 8250 as
Bus 002 Device 002: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode)

I tried to flash the firmware using the below command

./qdl --debug --storage ufs/rawprogram0.xml ufs/patch0.xml ufs/rawprogram1.xml ufs/patch1.xml ufs/rawprogram2.xml ufs/patch2.xml ufs/rawprogram3.xml ufs/patch3.xml ufs/rawprogram4.xml ufs/patch4.xml ufs/rawprogram4.xml ufs/patch4.xml ufs/rawprogram5.xml ufs/patch5.xml

which gives me error

qdl: firehose operation timed out

Any help in this regard is much appreciated
