Hi Gordon, i am using latest firmware.....

i will try using "trace"....

Hi Gordon,
I am trying to update my application over the air... to do that i am reducing my application size by keeping module in the main firmware.....
coming to Out of memory..... if i am using" Nrf.Sendstring();" i am facing the problem...when i am calling this i am checking "process.memory().usage" it is continuously decrementing....
how to control this.....

Hi I am trying to use NRF module... I am inserted NRF module as a variable in "LIB/jswrap_***.c" file
and i am getting that variable data and using "eval" to use that module... up to some time it is working good...
but after some time i am getting "Out of memory while appending to array"
what exactly this means? what things we need consider to get out of this problem.....

Here i am attaching the file which i am using in firmware...

Hi Gordon its working... Thank you....

Hi Gordon Thanks for the information ..... i will check it ...

Hi Gordon and DrAzzy,
there is no reason to use "mode" (at startup i dont know about the mode in SPI class .. )
That's why i modified in "jshSPISetup()". I can use mode there is no problem..

Coming to C code which i have attached, it is "KEIL" project... i am using that project just to write in to M25p16... as a Reference i am using.... (even we can read using that project)....

Hi allObjects,

hi i have uploaded C Code na using that i am writing to flash.... after that i am reading from the flash and erasing ....
i hope you got it...
and one thing i forgot to mention ....
i have modified this one to

 SPI_InitStructure.SPI_CPOL = (inf->spiMode&SPIF_CPOL)?SPI_CPOL_High:SPI_CPOL_Low;
  SPI_InitStructure.SPI_CPHA = (inf->spiMode&SPIF_CPHA)?SPI_CPHA_2Edge:SPI_CPHA_1Edge; 

like this

 SPI_InitStructure.SPI_CPOL = SPI_CPOL_High;
SPI_InitStructure.SPI_CPHA = SPI_CPHA_2Edge;

i have modified this in Espruino SPI_init();

Thanks & Regards
Vishnu

Hi Drazzy and allObjects,
eeprom.isBusy(); in this function i am using WREN that's why i commented it in write operation . As i am using

AT25.prototype.writedata= function(add,data,num) 
{
  
   eeprom.isBusy();
   eeprom.page_erase();
   console.log("\r\n page erased");
   eeprom.isBusy();
   eeprom.write(add,data); 
};

this one .In this first i am erasing the page and trying to write...

Hi Drazzy and allobjects,

as the same discussion is going on in FOTA (converstion ) . .. please move this one to [http://forum.espruino.com/conversations/261833/#comment12080855]

Hi DrAzzy and allObjects,

and the Java Script which i am trying to access M25p16..
As you mentioned i am trying to read write protect register...
but no luck with write operation.... Page Erase is working... reading is working.. but unable to do write() operation ...

Hi,

I am trying the same thing ....able to read() from M25p16 spi flash..... but i am unable to write to my M25p16 spi flash
i am checking that....

Hi DrAzzy,
Using AT25 module i am able read the flash... but write() is not working.. i am working on that.. mean while if you got any thing about this please update...

Thanks & Regards

Hi DrAzzy , Main Goal of the project is , i would like to update application (Java Script) by sending it over the TCP using GSM modem. To do this initially i am sending my code from a Serail3 (The same code which i will receive from the GSM (TCP)) . As you said i am sending save(); along with the code.. After that i am doing Reset(); and Load(); then i am checking the Application with dump() .. at that time i can see my OLD and New code both

Thanks
Vishnu

Hi thank for the reply... If I reset before eval I will loose the variable(code).. Any other suggestions...
