HL8548 Firmware Upgrade

[cgm_sys]

Hello,

what is the correct way to upgrade the fimrware of the HL8548?

I’ve tried to use the upgrade tool, but I get the following:

Use Port: USB1

Intel Command Line FlashTool v.1.37 (Download Library v.4.140,0.0 )

psi.fls (PSI) (NAND)
slb.fls (SLB) (NAND)
AENEAS_FW.fls (Code) (NAND)
SAM_6260.fls (Code) (NAND)
SAM_6260-MSY.fls (Code) (NAND)
SAM_6260-CDS.fls (Code) (NAND)
Booting ‘C:\Users\hartmann\AppData\Local\Temp\7zSC728.tmp\temp\psi.fls’, memclass: PSI
→ Please reboot your phone device ←

when I restart the module nothing happens. USB1 is present in device manger.
Would it be possible to use der serial port? There is no spec for command line

I would guess USB1 appears to late for bootloader handshake?

best regards

So, I’ve managed to use AirVantage to do a FOTA. But Airvantage list for firmware:

AlphaHL8548(BHL85xx.5.5.2.2) (BHL85xx.5.5.2.2.201407091825.x6250_1)

and I can’t upgrade to 5.5.20.x Version from the download section. So is this an alpha hardware or software limitation and what can I do?

ATI9 gives me

BHL85xx.5.5.2.2.201407091825.x6250_1 2014/07/15 16:58:13r1852 0
