I compiled stm32flash[1] under FreeBSD 8.4-STABLE:
tingo@kg-core1$ uname -a
FreeBSD kg-core1.kg4.no 8.4-STABLE FreeBSD 8.4-STABLE #0 r253646: Thu Jul 25 10:12:31 UTC 2013
root@kg-core1.kg4.no:/usr/obj/usr/src/sys/GENERIC amd64
The resulting binary appears to work:
tingo@kg-core1$ ./stm32flash
stm32flash - http://stm32flash.googlecode.com/
ERROR: Device not specified
Usage: ./stm32flash [-bvngfhc] [-[rw] filename] /dev/ttyS0
-b rate Baud rate (default 57600)
-r filename Read flash to file
-w filename Write flash to file
-u Disable the flash write-protection
-e n Only erase n pages before writing the flash
-v Verify writes
-n count Retry failed writes up to count times (default 10)
-g address Start execution at specified address (0 = flash start)
-f Force binary parser
-h Show this help
-c Resume the connection (don't send initial INIT)
*Baud rate must be kept the same as the first init*
This is useful if the reset fails
I have an STM32 board connected to cuaU0/ttyU0:
tingo@kg-core1$ ls -l /dev/cuaU* /dev/ttyU*
crw-rw---- 1 uucp operator 0, 159 Aug 18 17:26 /dev/cuaU0
crw-rw---- 1 uucp operator 0, 160 Aug 18 17:26 /dev/cuaU0.init
crw-rw---- 1 uucp operator 0, 161 Aug 18 17:26 /dev/cuaU0.lock
crw-rw---- 1 root operator 0, 156 Aug 18 17:26 /dev/ttyU0
crw-rw---- 1 root operator 0, 157 Aug 18 17:26 /dev/ttyU0.init
crw-rw---- 1 root operator 0, 158 Aug 18 17:26 /dev/ttyU0.lock
and my user has access:
tingo@kg-core1$ id
uid=1001(tingo) gid=1001(users) groups=1001(users),0(wheel),5(operator)
Still it doesn't work:
tingo@kg-core1$ ./stm32flash /dev/cuaU0
stm32flash - http://stm32flash.googlecode.com/
/dev/cuaU0: No such file or directory
tingo@kg-core1$ ./stm32flash /dev/ttyU0
stm32flash - http://stm32flash.googlecode.com/
/dev/ttyU0: No such file or directory
t doesn't work as root either, so it doesn't look like a permissions problem.
BTW, stm32flash with the same board and cable works nicely under Linux. Any hints on what could be wrong?
