IMX8QM: Wi-Fi firmware download error while reset the board

[vinothkumars]

Hi All,

Hardware: IMX8QM Custom Board + 88w8987 chipset

Software: Yocto - L 5.10

I am facing wifi firmware load error while software reboot and hardware reset, not in on and off the board.

And also I am not handling any reset configuration from device tree.

Please find the log and let me know what I missing,

Hi Vinothkumar

one can try to reset 88w8987, for example in AzureWave AW-CM358SM (it was used for

testing 88w8987 as described in Table 67. On-board chips and external solutions for Bluetooth and Wi-Fi support   i.MX Linux User’s Guide​ )  it is signal PDn described on p.13 datasheet
