AD9364 - Firmware crashes when using CMOS TDD mode

I want to operate the reference design in CMOS, TDD mode using the NO-OS firmware. However, when in CMOS mode (disable lvds_mode_en -- line 187 in the listing -- flag in init params) I can consistently get the firmware to fail on the next SPI transaction after the ad9361_init(); sequence.

I am using the example project from the NO OS drivers, 2019_r2. Line 3 in this listing is where the firmware fails in CMOS mode.

	ad9361_init(&ad9361_phy, &default_init_param);

	ad9361_set_tx_fir_config(ad9361_phy, tx_fir_config);
	ad9361_set_rx_fir_config(ad9361_phy, rx_fir_config);
    ad9361_trx_load_enable_fir(ad9361_phy, rx_fir_config, tx_fir_config);

More specifically, the fail can be found in ad9361_set_tx_fir_config() -> ad9361_load_fir_filter_coef() -> ad9361_ensm_force_state() -> 

dev_ensm_state = ad9361_spi_readf(spi, REG_STATE, ENSM_STATE(~0));

	ad9361_spi_write(spi, REG_ENSM_CONFIG_1, TO_ALERT | FORCE_ALERT_STATE);

	rc = ad9361_spi_write(spi, REG_ENSM_CONFIG_1, val);
	if (rc) {
		dev_err(dev, "Failed to write ENSM_CONFIG_1\n");
		goto out;
	}

	while (ad9361_ensm_get_state(phy) != ensm_state && --timeout) {
		no_os_mdelay(1);
	}

	if (timeout == 0)
		dev_err(dev, "Failed to restore state");

out:
	return;

}

However, if I change this lvds_mode_en flag back to 1 (leaving everything else the same), the firmware runs as expected, and all SPI writes behave like normal.

I'm confused why the system would fail on a SPI read for the ENSM, as I'm not sure it has anything to do with CMOS/LVDS mode, is that correct? It also appears to run through all of the SPI read/writes in the ad9361_init() sequence with no problems.

Is there some change in the reference design that needs to be made to support CMOS mode? If so, what are those changes exactly? Or is there some firmware code that can be added to resolve this issue?

EDIT: I've found that when in CMOS mode the ad9361_dig_tune_delay() function in the ad9361_post_setup() routine fails, but I'm not sure what is causing it to fail. Is the reference design not set up for this, or is there some setting I can use to operate in CMOS mode? 



Added progress on issue: fail on ad9361_dig_tune_delay()
