The invention discloses a dual-core controller online upgrading
system of DSP and ARM based on WIFI and a method thereof. The
system comprises servers,
wireless routers and several devices; the deviceincludes ARM, DSP and a WIFI module. The device establishes
wireless connection with a
wireless router through the WIFI module, the
wireless router and the
server establish
communication link, and ARM connects with DSP through an SPI
bus. The internal FLASH of ARM has four regions: A, B, C and D. The A region is used to store the BootLoader of ARM, the B region and the
C region are used to storethe user program, the D region is used to store the related parameters. DSP includes internal FLASH,
internal RAM, and external SRAM. The invention has the following beneficial effects: 1, the invention can
upgrade the DSP and the ARM of the controller at the same time; 2, the
peripheral circuit of the
upgrade system in the invention is simple, and the remote
upgrade can be realized without complex circuit; 3, the
software of the host compute in the invention supports upgrade DSP or ARM program separately; 4, the upper
computer software of the invention supports the simultaneous batch online upgrade program.
