USB/UART Driver - Red Hat

mlheese — Wed, 17 Jan 2024 15:43:52 GMT

I have the ublox EVK-JODY-W263 WiFi/BT Eval Board with NXP 88W8987 Chipset.

The board has a USB/UART Cable interface so it can be connected to a host machine for evaluation/testing. The Host Machine I'm using has an Intel Processor running Red Hat 8 (64-bit).

Where can I find the Driver for the USB/UART interface so I can use this board on my Red Hat machine?

U-blox docs say that U-blox provides them but when I contact U-blox they point me towards NXP and Yocto. The Yocto repos only have the recipes for creating deployable images, which is not what I'm doing. I just want the driver for the USB/UART interface to work with my Red Hat machine.

I'm probably misunderstanding this but would appreciate any help.

I understand that on ublox page https://www.u-blox.com/en/product/evk-jody-w2#Documentation-&-resources?legacy=Current?legacy=Current, you checked EVK-JODY-W2_UserGuide https://content.u-blox.com/sites/default/files/EVK-JODY-W2_UserGuide_UBX-19027118.pdf in which chap 1.3 refers to "JODY-W2 system integration manual" for drivers building (https://content.u-blox.com/sites/default/files/JODY-W2_SIM_UBX-18068879.pdf). chap 3.5 explains how to compile the drivers but it is not matching your needs.

Thank you. That package has the source for:
wlan_src/mapp
wlan_src/mlinux
wlan_src/mlan
muart_src
uartfwloader_src

What is still missing is the Source for the different Bluetooth Drivers 'bt8987.ko'. The documentation says these are in 'SD-BT-src.tgz' and 'SD-BT-CHAR-src.tgz' but neither is in the package you referenced? Is this in a separate package?

I see that you refers to ublox doc "JODY-W2_SIM_UBX-18068879.pdf".

I suppose that the package you are speaking of was downloaded from nxp site page https://www.nxp.com/products/wireless/wi-fi-plus-bluetooth/2-4-5-ghz-dual-band-1x1-wi-fi-5-802-11ac-plus-bluetooth-5-2-solution:88W8987?SAMLart=ST-AAF0E3YJDJej%2BJVBprc7Vu5rkUdezztq%2FP8BbEPb3lEpK4Y%2BljdFy3b6#software ?

Release "SD-WLAN-UART-BT-8987-U16-X86-16.92.21.p41.4-16.92.21.p41.4-MM5X16344.P3-MGPL" for instance ?
So, I suggest that you preferably follow nxp doc found on the same page in https://www.nxp.com/products/wireless/wi-fi-plus-bluetooth/2-4-5-ghz-dual-band-1x1-wi-fi-5-802-11ac-plus-bluetooth-5-2-solution:88W8987?SAMLart=ST-AAF0E3YJDJej%2BJVBprc7Vu5rkUdezztq%2FP8BbEPb3lEpK4Y%2BljdFy3b6#documentation : "WLAN Bluetooth Setup and Debug User Guide"
