Is there any other packages supporting debugging, monitoring, data
logging, flash programming of embedded systems?
Don't know about JTAG, but I've successfully used a TBDML interface from
Python to control S12 microcontrollers via BDM.
Basically, any BDM or JTAG interface should have a DLL as driver which
you can import using ctypes.
Sorry, hit the wrong button...
Low level usage via ctypes looked like this:
import ctypes
tbdml = ctypes.windll.LoadLibrary("tbdml.dll")
# connect
tbdml.tbdml_init() # returns number of devices
tbdml.tbdml_open(0)
tbdml.tbdml_target_sync() # returns 0 on success
# play with micro ports
tbdml.tbdml_write_byte(0x0,2) # set port
tbdml.tbdml_read_byte(0x0) # read back
With a small wrapper around, usage looked like this:
import TBDML
t = TBDML.TBDML(device_no=0);t.target_sync();t.target_reset(0)
t[0x00] = 2
print t[0x00]
If that's what you need, contact me.
