francesco@Gemstone:~/Programmi/IAR/sflash$ gcc -o sflash packet_handler.c uart_handler.c sflash.c francesco@Gemstone:~/Programmi/IAR/sflash$ ./sflash -h Usage: sflash filename -p [program address] -r [execution address] -c [tty] -d -l [Boot Loader filename] -b [baud rate] -s [data size] -p [program address]: if address is not specified it is assumed to be 0x00000000 if there is no 0x prefix is added then the address is assumed to be in decimal -r [execution address]: if address is not specified then no run command will be sent. -c [tty]: This is the name of the TTY device to use. -l [Boot Loader filename]: This specifies a boot loader binary that will be loaded to the device before downloading the application specified by the filename parameter. -b [baud rate]: Specifies the baud rate in decimal. -d Disable Auto-Baud support -s [data size]: Specifies the number of data bytes to be sent in each data packet. Must be a multiple of 4 between 4 and 252 (inclusive). Example: Download test.bin using COM 1 to address 0x800 and run at 0x820 sflash test.bin -p 0x800 -r 0x820 -c 1
