WIZ-iRadio User’s Manual 4. Firmware description 4.1. Firmware Structure The firmware of WIZ-iRadio is composed of Application and Boot. The role of Boot is for updating through the network. Therefore, JTAG ICE such as MultiICE is not required when developing. In the WIZ-iRadio, STR710FZ2 from STMicroelectronics is used. In the Flash of this MCU, Application and Boot firmware is written according to the memory map (below).
PAGE 16
WIZ-iRadio User’s Manual There are RAM_MODE and FLASH. In the case of RAM_MODE, it is used for operating at the internal RAM after writing the F/W and downloading with JTAG device such as MultiICE. The FLASH is used for operating after writing in the flash memory of STR710FZ2. You can select one of them. For the not-used mode, mark it as commentary. The program starts from 0x400300000 of flash memory at the Boot. The scat file in the Boot folder is as below (please refer to Figure 9). 16 Figure 9.

WIZ-iRadio User’s Manual 22 Figure 15. Compile - 6 After finishing compile, “network.axf” file is created in the folder of “REALVIEW\Debug”. In order to change this file to binary format, use ‘fromelf’. You can do it as below. It is created in the file “bin.bat” fromelf -bin -o network.bin network.axf After changing the file “network.axf” file to “network.bin”, if you execute “ROM_Tool.exe” program and input this file, “rom.bin” file is created in the folder of “romfile”. The role of “ROM_Tool.

WIZ-iRadio User’s Manual This “rom.bin” file can be updated through network by using Configuration Tool. 4.4. Firmware Operation Process 1) Initialize device a. GPIO b. Clock c. Setting EMI(External Memory Interface) CS1 for W5100, CS2 for external SRAM and CS3 for LCD d. Timer e. DMA request of VS1033 f. SPI interface for VS1033 g. I2C for EEPROM h.
PAGE 24
WIZ-iRadio User’s Manual 1) Initialize device When power is supplied, all devices are initialized. GPIO is configured and clock is set. In regard to external memory interface, CS1 is connected to W5100, CS2 is to SRAM and CS3 is to LCD. According to this interface, set the ‘wait’ and ‘bus’ size. Timer 0 is used for DHCP request during lease time, and Timer 1 is for operation of IR Remote Controller. VS1033 chip used for decoding of MP3 and WMA is connected to MCU by SPI. The interrupt should be set.

WIZ-iRadio User’s Manual Most of the function of F/W checks the socket status and performs the related activities. If the address of broadcasting station is of domain name, by using DNS protocol, communication with DNS server is processed to acquire real IP address. After connecting to this IP address, it sends the data to check if the server operates with the method of SHOUTCAST or HTTP. In case of MMS, the address starts with ‘mms://’.
