[File]
h8comm is a program to write flash memory of H8/3048F by boot mode. It
communicates to H8 via serial line.
Normally, it executes following steps:
-
h8comm sends a boot-strap program to H8 using H8/3048F boot-mode protocol.
-
The boot-strap program reads target codes from serial line, and writes to flash
ROM.
-
h8comm sends data in stdin to the serial line, and shows data to stdout
received from the serial line.
These steps can be disabled by command-line options.
- -h
-
Show summary of options.
- -D device
-
Specify serial device. Default is /dev/ttyS1
- -r file
-
Specify the binary image file of the boot program. Default is
/usr/local/lib/h8comm/h8prog.bin
- -b BPS
-
Specify the baudrate of the serial line after the boot-strap program is
executed. It must be 2400 or more, and is rounded to the appropriate value.
Default is 9600.
- -B BPS
-
Specify the baudrate of the serial line. It must be 2400 or more, and is
rounded to the appropriate value. Default is the same value as -b.
- -n
-
Do not send ROM image of a main program. Only a boot-strap program is
executed.
- -d
-
Monitors the serial line After writing to ROM. This is useful if your programs
uses serial line as standard input/output.
h8comm sample.bin
Writes sample.bin
to H8 ROM. This is a standard usage of h8comm.
h8comm -r sample.bin -n
Executes sample.bin
as a boot-strap program. It is useful to test
small programs.
