Question regarding removal of W8997 firmware from imx-firmware Hello NXP team, I’m contacting you regarding the following commit in the imx-firmware repository: “Remove SD/PCIE W8997 support from BSP from 26Q1 onwards” Could you please clarify whether the W8997 firmware was only removed from the standard imx-firmware package or wheter support for these devices has been discontinued entierly ? We can retrieve the last W8997 firmware files from the Git history, so our main question is about the recommended way to maintain W8997 support while continuing to use the latest imx-firmware releases. Is it supported to install the latest imx-firmware package and add the W8997 firmware files from the last release that contained them? If so, is there any recommended procedure or packaging approach to do this cleanly and avoid conflicts with future imx-firmware updates? Our goal is to keep systems on the latest i.MX firmware package while preserving support for older deployed hardware based on the 88W8997. Best regards, Antoine Gennart Re: Question regarding removal of W8997 firmware from imx-firmware Hello @agennart, hope you are doing well.
I'm checking this with the internal team. I will get back to you once I get a response. Re: Question regarding removal of W8997 firmware from imx-firmware Hi @agennart,
Could you please provide more details on your project? As well as the W8997 module that you are using and the interface you have implemented (PCIe or SDIO). Re: Question regarding removal of W8997 firmware from imx-firmware I don't have a project using W8997. I am trying to bump the `imx-firmware` version in the Buildroot project. Buildroot aims to maintain compatibility with older hardware, while also supporting newer hardware, hence the update. The problem is that this update would break compatibility with older hardware, so I need a way to preserve that compatibility. I see two possible scenarios: 1. NXP has simply removed support for the older hardware. In that case, the Buildroot project needs a way to select the appropriate version of `imx-firmware` in order to maintain compatibility with older hardware. 2. NXP has moved support for the older hardware to another package/project. In that case, the Buildroot project needs to update or integrate that package/project to maintain compatibility. Re: Question regarding removal of W8997 firmware from imx-firmware Hi @agennart,
Support for 88W8997 will be provided through dedicated hotfix branches on Github for both W8997 drivers and firmware based on the LF 6.12.49_2.2.0 release baseline. These branches will contain all future off-cycle releases targeting W8997. Hence, you may update your environemnt to reference the below hotfix branches:
Driver branch - GitHub - https://github.com/nxp-imx/mwifiex/tree/hotfix/lf-6.12.49_2.2.0_hotfix_w8997
Firmware branch - GitHub -https://github.com/nxp-imx/imx-firmware/tree/hotfix/lf-6.12.49_2.2.0_hotfix_w8997
For compatibility with W8997, the suggested path is to point to the shared hotfix branches as the main branch will not receive further support for this device.
Please let me know if this information fits your requirements.
