Hit stall for buffer error occurs while reading RX1 continuously
Hi. I am using BladeRF via Python but each time I try reading RX1 continuously I get this error after some time spent:
[ERROR @ host/libraries/libbladeRF/src/backend/usb/libusb.c:1071] Hit stall for buffer 000001AB9DF003E0
Here is a code I am using to get the RX data (self.rx_samples_num = 2048):
self.device.sync_config(layout = _bladerf.ChannelLayout.RX_X1,
fmt = _bladerf.Format.SC16_Q11,
num_buffers = 2,
buffer_size = 2048,
num_transfers = 1,
stream_timeout = 3500)
# Enable module
self.postMessage( "RX: Start" )
self.rx_ch.enable = True
# Get the samples
num = self.rx_samples_num
while _thread.isRunning():
# Read into buffer
time.sleep(0.04)
self.lock.acquire()
try:
self.device.sync_rx(self.rx_buf, num)
except _bladerf.BladeRFError:
self.postMessage( "RX error.")
self.lock.release()
# Draw the data
if self._drawn:
_thread._draw_signal.update.emit()
self._drawn = False
# Disable module
self.postMessage( "RX: Stop" )
self.rx_ch.enable = False
self.rx_ch = None
This code is being executed by a separate thread.
IMPORTANT: The error occurs not instantly but some time after start. It disables the device and "try: except" section does not help in catching of it.
