X-NUCLEO-ST67W61 + STM32N6570-DK - waiting for spi txn ready timeouted

[Shirovaty]

Hello, as in the title I'm facing issues with high intensity BLE transfers (~4 writes and 4 reads and indicates per second) on X-NUCLEO-ST67W71 paired with STM32N6570-DK.
Randomly during the transfer I'm encountering this error which simply breakes the communication with ST67:

ST67 Log: [ERROR] [1055938] [spi_xfer_engine] (spi_iface.c:448) waiting for spi txn ready timeouted
ST67 Log: [ERROR] [1057938] [spi_xfer_engine] (spi_iface.c:448) waiting for spi txn ready timeouted

That's the setup for the SPI5, which is used to communicate with ST67:

 hspi5.Instance = SPI5;
 hspi5.Init.Mode = SPI_MODE_MASTER;
 hspi5.Init.Direction = SPI_DIRECTION_2LINES;
 hspi5.Init.DataSize = SPI_DATASIZE_8BIT;
 hspi5.Init.CLKPolarity = SPI_POLARITY_LOW;
 hspi5.Init.CLKPhase = SPI_PHASE_1EDGE;
 hspi5.Init.NSS = SPI_NSS_SOFT;
 hspi5.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_64;
 hspi5.Init.FirstBit = SPI_FIRSTBIT_MSB;
 hspi5.Init.TIMode = SPI_TIMODE_DISABLE;
 hspi5.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
 hspi5.Init.CRCPolynomial = 0x7;
 hspi5.Init.NSSPMode = SPI_NSS_PULSE_ENABLE;
 hspi5.Init.NSSPolarity = SPI_NSS_POLARITY_LOW;
 hspi5.Init.FifoThreshold = SPI_FIFO_THRESHOLD_01DATA;
 hspi5.Init.MasterSSIdleness = SPI_MASTER_SS_IDLENESS_15CYCLE;
 hspi5.Init.MasterInterDataIdleness = SPI_MASTER_INTERDATA_IDLENESS_15CYCLE;
 hspi5.Init.MasterReceiverAutoSusp = SPI_MASTER_RX_AUTOSUSP_DISABLE;
 hspi5.Init.MasterKeepIOState = SPI_MASTER_KEEP_IO_STATE_ENABLE;
 hspi5.Init.IOSwap = SPI_IO_SWAP_DISABLE;
 hspi5.Init.ReadyMasterManagement = SPI_RDY_MASTER_MANAGEMENT_INTERNALLY;
 hspi5.Init.ReadyPolarity = SPI_RDY_POLARITY_HIGH;

 And the SPI5 is handled through GPDMA1
Worth mentioning: ST67 is running 2.0.89 binary, X-CUBE-ST67 is v1.1.0

If there is anything more to be provided in terms of info, just let me know!
