"could not write to the device EFS"

[walterm]

Hi,

I want to upload a BREW application onto LG VX6000. I got everything (sig, mod, mif, bid, qres) in a PC directory where I can upload a module into the handset. But, this message appears, "could not write to the device EFS", what does this mean? Is my handset locked so I can't upload appplications? How did you guys upload your application? Do you need to go through Commercializaiont Compliers process to get the application into ARM binary form mentioned in the "Test on BREW Device" secttion before getting a sig file? Because I didn't, I got the sig file generted directly.

Also, what's the difference bet. RealView Compilation Tools for BREW and GNU Cross Compiler? Do I need to use them both, or just one is enough and which one is the better one?

Thank you in advance.

Hi !

I'm trying to pupload my ARM compiled files to the New test enabled T720 device, and I can create folders in theroot, But when i try to upload any files, .mif -> "/" and .mod, .bar, .sig -> "/myapp/". It throws an

"Error - Low Level EFS operation failed. Could not write to the device EFS"

Whyis this error comming, and how will i get it the files inside the t720 ?? I can get connected to t720 as it shows that the device is connected with the apploader and only thing is that my files are not getting loaded.

What shall i do, please help me with suggestons ASAP !!

Thanks in advnce.

joy, phone might not be test enabled. send it to qualcomm, even if they said it is ;)
(presuming the EFS isn't full), hard resetting it might fix it, but that may also clear the test bit, it does on some phones.

RealView is made by ARM for ARM processors, GCC is made by hippies and/or students ;) , well ok ARM is a lot of that too.

RealView just works, the full version comes with some good tools and it generates smaller and faster code nearly all of the time.

Either will work, GCC as with most *nix stuff can take a lot to setup.

if 'free' means better then GCC
if source code of the compiler etc is required then GCC
if it means code size/speed and less setup hassle then ARM
if compiler technical support then ARM
tools, i like the ARM better, it has nice tools but you need to full version, GCC does have a lot of backend tools available though but not as pertinent

(windows only considered)

the code/size is enough to forget about GCC for me, well that and maybe all those tortuous years using GCC on PSX/N64/GC etc
