@christoph2 pyxcp == 0.22.23 , shortUpload function often gets the Shortupload value as feedback from other messages, resulting in incorrect values returned. Can I fix this? The version of pyxcp-0.21.11 I used before is OK, I hope you can help me, thank you very much ~

my pyxcp_conf.py is :
c = get_config() # noqa

c.Transport.Can.Vector.serial = 529423 #CAN serial

c.Transport.Can.poll_interval = 0.001
c.Transport.Can.Vector.serial = 32634 #CAN serial
c.Transport.layer = 'CAN'
c.Transport.Can.padding_value = 0xAA
c.Transport.Can.use_default_listener = True
c.Transport.create_daq_timestamps = False
c.Transport.Can.Vector.rx_queue_size = 16384
c.Transport.Can.can_id_broadcast = 256
c.Transport.Can.interface = 'vector'
c.Transport.Can.max_dlc_required = True
c.Transport.Can.use_default_listener = True
c.Transport.Can.can_id_master = 0x580 # Master CAN ID
c.Transport.Can.can_id_slave = 0x581 # Slave CAN ID
c.Transport.Can.channel = 0 # CAN channel (e.g., 0 for Kvaser channel 0)
c.Transport.Can.bitrate = 500000 # CAN bitrate
c.Transport.Can.fd = True # CAN bitrate
c.Transport.Can.receive_own_messages = True # CAN bitrate
c.Transport.Can.data_bitrate = 2000000 # CAN bitrate
c.Transport.Can.sjw_abr = 8 # CAN bitrate
c.Transport.Can.tseg1_abr = 31 # CAN bitrate
c.Transport.Can.tseg2_abr = 8 # CAN bitrate
c.Transport.Can.sjw_dbr = 8 # CAN bitrate
c.Transport.Can.tseg1_dbr = 31 # CAN bitrate
c.Transport.Can.tseg2_dbr = 8 # CAN bitrate

The interesting thing here is the -1:
The variable in question Master.slaveProperties.maxCto is set after a CONNECT service and one can expect a reasonable value for MAX_CTO, like 8 on CAN classic, but it seems to be zero here. A correct value is vital for block transfer, DAQ allocation and other things.

Could you run xcp-info and look for maxCto?

{'addressGranularity': EnumIntegerString.new(0, 'BYTE'),
 'byteOrder': EnumIntegerString.new(0, 'INTEL'),
 'bytesPerElement': 1,
 'interleavedMode': False,
 'masterBlockMode': False,

 'maxCto': 8,
 'maxDto': 8,
 'maxWriteDaqMultipleElements': 0,
 'minSt': 0,
 'optionalCommMode': True,
 'pgmProcessor': {},
 'protocolLayerVersion': 1,
 'queueSize': 0,
 'slaveBlockMode': True,

 'supportsDaq': True,
 'supportsPgm': True,
 'supportsStim': False,
 'transportLayerVersion': 1,
 'transport_layer': 'CAN',
 'xcpDriverVersionNumber': 10}

And could you also put a print statement in your code?

print(x.slaveProperties)
