argument 3: <class 'TypeError'>: Don't know how to convert parameter 3 when running flash

[SoftubeBask]

Hello,

Upgraded from 0.11 to the latest (1.2.0) and get the error when trying to flash the target. I've tried to change the parameters but get the same error.

` def on_progress_cb(self, action, progress_string, percentage): if progress_string is not None: print(progress_string)

payload = progress_string.decode('utf-8')

        # message:DataType = DataType(interface=InterfaceEnum.CONTROL, target=TargetEnum.VERTIGO, data=self.create_message("PROGRESS", payload))
        # self.queue.put(message)
        # time.sleep(0.1) # Wait to make sure that this packet is sent alone

def flash_image(self, address, image):
    try:
        interface_swd = 1
        jlink_target = pylink.JLink()
        jlink_target.open()
        jlink_target.oem
        jlink_target.set_tif(interface_swd)

        jlink_target.connect("MIMXRT1021DAG5A", verbose=True, speed=4000)
        jlink_target.reset()
        jlink_target.halt()

        print(address)
        print((int(address, 16)))
        jlink_target.flash(image, (int(address, 16)), on_progress=self.on_progress_cb)
        jlink_target.reset()
        self.logger.write(self, "  - Flashing Done!")`

Raw address is 0x60000000 and converted to int it is 1610612736. What am I missing?

Can you post the full traceback?

Sure, here is the traceback:

The issue seems to be with image, and not the address, as the data is the third argument to WriteMem(). What is the type of image that you pass in here?

        jlink_target.flash(image, (int(address, 16)), on_progress=self.on_progress_cb)

Oh, okay. It's a bytearray

[hkpeprah]

Can you try converting it to bytes?

>>> b = bytearray([1, 2, 3])
>>> type(b)
<class 'bytearray'>
>>> b
bytearray(b'\x01\x02\x03')
>>> b = bytes(b)
>>> type(b)
<class 'bytes'>
>>> b
b'\x01\x02\x03'

Tested to convert it to a list and don't get the exception now at least but I am remoting to the computer with the hardware, so i'm not able to confirm that the hardware boots. But whatever it is, it's probably my conversion to list that would be the culprit if there is any issues. Thank you for your speedy help!
