Subject: [PATCH v3] Enable wifi on the BeagleV-Ahead
Date: Thu, 14 May 2026 16:47:17 +0200	[thread overview]
Message-ID: <20260514144836.50101-1-thomas.gerner@muenchen-mail.de> (raw)
In-Reply-To: <20260512173440.163179-1-thomas.gerner@muenchen-mail.de>

The BeagleV-Ahead board uses an AP6203BM WiFi chip from AMPAK Technology
Inc. connected to SDIO1. The chip is compatible to the broadcom wireless
driver.

The AP6203BM is a dual-band 2.4GHz/5GHz Wi-Fi 4 (802.11a/b/g/n) and
Bluetooth 5.4 module. Bluetooth is not enabled by this patch.

Change in v3:
- consider further issues found by sashiko AI review

Change in v2:
- consider issues found by sashiko AI review
