Can you provide more explanations on the flow, if I look at the code I only see that this will load the firmware and library, which looks like the re-doing the start of this function set_dsp_D0, it doesn't seem to retry a boot so not sure in what state the DSP lands and if all the control variables such as boot_complete are set.
if (ret < 0) {dev_err(ctx->dev, "Reload fw failed: %d. Failed to set core0 to D0 state\n",ret);goto err;
is there a reason why you removed the ret = -EIO assignment?
