Date: Wed, 26 Aug 2020 16:20:44 -0700 Message-Id: <20200826232044.6799-1-greearb@candelatech.com> MIME-Version: 1.0 List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: "ath11k" Errors-To: ath11k-bounces+kvalo=adurom.com@lists.infradead.org To: ath11k@lists.infradead.org Cc: Ben Greear , linux-wireless@vger.kernel.org From: Ben Greear The QCA6390 board I have, model 8291M-PR comes with an ELF board file. To get this to at least somewhat work, I renamed bdwlan.e04 to 'board.bin' and then added this patch to check for .ELF as starting bytes of the board file. If that is found, use type ELF. After this the driver loads.
