The size of call hold music data in page5 -- page7 must be 192K(3×64K), namely 196608
bytes, and the filename format is holdmusic_xxx.dat, where xxx are any strings.
The size of font data in page8 -- page11 must be 256K(4×64K), and the filename format
is font.dat.
page12 – page31
This part is for main program, protocol program, http data and DSP data.
page12 – page31 are divided into 2 parts with the same contents, which is a safety
characteristic of the AR1688. page12 – page19 is section 1 and the data starts in page 12.
page22 – page31 is section 2 and the data starts in page 22. We distinguish the two parts
from each other by the configuration option "system_page". When configured as
"system_page=12", the phone will boot from section 1 and from section 1 and let the
phone program update the software in section 2. When it is set to "system_page=22", the
phone will boot from section 2 and let the phone update the software stored in section 1.
By separating and duplicating the software, we avoid failures that could be caused by any
errors that may occur while the program is updating.
The space for phone main program, http data and DSP data are 10 pages, namely 10×
64K＝640K, and the programs run in corresponding section according to flag setting.
Pages of this part are as follows:
page12 -- page15: phone main program;
page16: for storing phone http data;
page17 -- page21: for storing phone DSP data;
page22 -- page25: the same as page12 -- page15.
page26: the same as page16;
page27 -- page31: the same as page17 -- page21;
Note:
Other pages are in development and reserved.
