Hiya, Is the application compiled with the appropriate ADL version for the firmware in your modem? Have a look at [viewtopic.php?f=108](https://forum.sierrawireless.com/t/hello-world-error-application-with-a-lower-start-address/5963/1) for some more notes on this. Also, have you got enough free A&D flash to accept the application you are downloading? ciao, Dave ---

Hi, > [@](#): > > Is the application compiled with the appropriate ADL version for the firmware in your modem? Yes it is an earlier Version of the apllication running on the moden. When i download it with at+wdwl it works. > [@](#): > > Also, have you got enough free A&D flash to accept the application you are downloading? all adl\_adwrites return 0 and the adl\_adfinalise returns 0. The dwl file is 103776 Bytes big, the same amount stored in the cell. I have read the notes an found no clues. I will now upload the file from the cell and compare it with the original. ---

i uploaded and downloaded the dwl file sha512sum.exe latest.dwl upload\_from\_device 8c32dfbcd9596e60c7926e4d80ca51be26e3089cff7c22a689bde7cc9f3c4744eba8b1cd3a5a0e948b8e803498c532bb4b632cdff27e6e9a916953505dcd5f4a \*latest.dwl 8c32dfbcd9596e60c7926e4d80ca51be26e3089cff7c22a689bde7cc9f3c4744eba8b1cd3a5a0e948b8e803498c532bb4b632cdff27e6e9a916953505dcd5f4a \*upload\_from\_device The sha512sum matches. I am now positive that the dwl file is correct. I send upload\_from\_device to the module with AT+WDWL and it works What about endianess ? Is BigEndian correct ? What about stacksize ? Here is whats running on the siwi module: 11:16:16:899 - “DWL”," SWI6200T\_02.02.04.05BT R2734 CNSZXD00000145 2013/07/19 15:03:02","",“Sierra Wireless”,0,"",“00000000”,“00000000” 11:16:16:914 - “FW”,“FW\_752\_28\_A1\_8.Q268Fx”,“R7.52.0.A1.201307191706.Q2698”,“Sierra Wireless”,1762020,“071913 17:06”,“cd354cd9”,“10002020” 11:16:16:930 - “MODEM 3G+”,“Revision: SWI6200T\_02.02.04.05AP R2734 CNSZXD00000145 2013/07/19 15:03:02” 11:16:16:930 - “OAT”,“1.0.0.20140131110436”,“3G”,“Rudolph-Industrie-Elektronik”,191600,“013114 11:05”,“2dcd71b5”,“10700000” 11:16:16:945 - -“Developer Studio”,“2.3.2.201310241548” 11:16:16:945 - -“Open AT Application Framework package”,“2.52.0.A1.201307221109” 11:16:16:961 - -“Open AT OS Package”,“6.52.0.A1.201306271522” 11:16:16:977 - -“Firmware Package”,“7.52.0.A1.201307191706” 11:16:16:977 - -“Internet Library Package”,“5.56.0.A1.201307011505” 11:16:16:977 - -“Location Library Package”,“1.4.6.201305151408” 11:16:16:977 - “ROM”,“8400000” 11:16:16:977 - “RAM”,“4000000” 11:16:16:977 - “DWLNAME”,“Q2698”
