Q: GX8008(C) serial port frequently prints Receive FIFO underflow interrupt.
A: The error comes from the MCU interface: flash_spi_irq_handler. The reason for this problem may be that the program has accessed illegal address, and software engineers need to query the memory access of the modified code Is it normal.

Q When using the UAC function, it is stuck and this message appears ERR : f_audio_set_alt invalid intf : 0

Q: DSP compilation error _1

     You need to either specify the name of a registered Xtensa core (with
     the --xtensa-core option or the XTENSA_CORE environment variable) or
     specify a different registry of Xtensa cores (with the --xtensa-system
     option or the XTENSA_SYSTEM environment variable).
     [Preparing vsp/dsp...]
     Error: the "GXHifi4_170719A_G1708" core is not in the current Xtensa core registry.
A: You need to correctly specify your own DSP compilation tool path in the compilation configuration of make menuconfig d
