This must be written to the EEPROM as ASCII hex in
eight (8) address blocks. The actual AT commands to
store this boot command in the EEPROM starting at hex
address 0000 are:
AT:M0000,4E,0D,41,54,3A,55,32,43
AT:M0008,2C,30,30,42,30,0D,0D,30
AT:M0010,38,30,0D,41,54,3A,55,36
AT:M0018,37,2C,30,30,30,43,2C,30
AT:M0020,30,31,30,2C,30,30,30,34
AT:M0028,0D,41,54,3A,55,34,44,2C
AT:M0030,30,30,31,0D,0D,0D
With this macro installed in the EEPROM, the
ATN<CR> command configures the modem for
operation in Norway.
Autoloading Firmware Upgrade Example
This example stores a firmware upgrade in EEPROM
that is automatically loaded into the modem after power-
up or hardware/software reset with a pulldown on the
D6 pin (Si2493/57/34/15/04 pin 4).
The AT commands required to load the firmware
upgrade manually are:
AT*Y254:W0050,0000<CR>
AT:PF800.08D5
To implement this as a boot command macro, the
commands are:
BOOT<CR>
AT*Y254:W0050,0000<CR>
AT:PF800.08D5
This must be written to the EEPROM as ascii hex in
eight (8) address blocks. The actual AT commands to
store this boot command in the EEPROM starting at hex
address 0000 are:
AT:M0000,42,4F,4F,54,0D,41,54,2A
AT:M0008,59,32,35,34,3A,57,30,30
AT:M0010,35,30,2C,30,30,30,30,0D
AT:M0018,41,54,3A,50,46,34,30,30
AT:M0020,2C,30,38,44,35,0D,0D,0D
Note that this firmware upgrade (patch) is only an
example meant to illustrate the procedure for loading a
patch into the EEPOROM. Loading this code into a
Si2493/57/34/15/04 causes undesirable behavior.
