bcm53xx: Linksys EA9500 issues #9414

Open Tentpig opened 2 years ago

Tentpig commented 2 years ago

I have attempted to flash 21.02.1 and 21.02.2 to a Linksys EA9500. While both flashed successfully, I am encountering errors which I can only classify as bugs in both releases.

First, in 21.02.2, after flashing, I am unable to connect via ethernet to 192.168.1.1, nor does it appear the Internet port attempts to get a DHCP address. When I watch the serial console during boot, I see the following message:

[    4.148865] kmodloader: done loading kernel modules from /etc/modules-boot.d/*
[    4.162578] init: - preinit -
Failed to connect to the switch. Use the "list" command to see which switches are available.

[    5.341711] bgmac_bcma bcma0:3 eth0: Link is Up - 1Gbps/Full - flow control off
[    5.349060] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

I downgraded to 21.02.1 and was able to get past this problem. However, 21.02.1 appears to have issues with configuring the wireless radios. It appears I can use any channel 112 or below on radios 0 and 2, but anything above 112 will yield the following error on the console:

[  171.434382] ieee80211 phy2: brcmf_cfg80211_start_ap: Set Channel failed: chspec=55414, -52
[  173.372503] device wlan2 left promiscuous mode
[  173.377053] br-lan: port 2(wlan2) entered disabled state
[  175.314988] br-lan: port 2(wlan2) entered blocking state
[  175.320322] br-lan: port 2(wlan2) entered disabled state
[  175.325915] device wlan2 entered promiscuous mode
[  175.332565] ieee80211 phy2: brcmf_run_escan: error (-52)
[  175.337897] ieee80211 phy2: brcmf_cfg80211_scan: scan error (-52)

Once the scan error appears, the only way to clear it is a reboot. Even changing the channel to something 'valid' will still generate the error.

I set my country code to US and am using 40Mhz widths.

According to the stock Linksys firmware, valid channel selections for the 2 5Ghz channels are 36, 40, 44, and 48 for Radio 0 and 149, 153, 157 and 161 for Radio 2.

Thanks, Vinny

I came across the same issue on the 21.02.x, so I tried 22.03.x

openwrt-22.03.0-rc1-bcm53xx-generic-linksys_ea9500-squashfs.trx works.

openwrt-22.03.0-rc2-r19374-34b6abf5a8-bcm53xx-generic-linksys_ea9500-squashfs.trx doesn't work.
