Hi, I was able to run firmware sd8801_uapsta.bin on kernel 4.19, but after upgrading to 5.10, that firmware is no longer functional, constantly connected / disconnected the WiFi modem: [ 2456.553366] mwifiex_sdio mmc0:0001:1: info: trying to associate to 'JupiterIoT' bssid 34:08:04:12:b1:a2 [ 2456.577515] mwifiex_sdio mmc0:0001:1: info: associated to bssid 34:08:04:12:b1:a2 successfully [ 2456.590492] mwifiex_sdio mmc0:0001:1: CMD_RESP: cmd 0x23f error, result=0x2 [ 2456.625367] mwifiex_sdio mmc0:0001:1: CMD_RESP: cmd 0x23f error, result=0x2 [ 2459.599572] mwifiex_sdio mmc0:0001:1: info: successfully disconnected from 34:08:04:12:b1:a2: reason code 2 [ 2461.889309] mwifiex_sdio mmc0:0001:1: info: trying to associate to 'JupiterIoT' bssid 34:08:04:12:b1:a2 [ 2461.915404] mwifiex_sdio mmc0:0001:1: info: associated to bssid 34:08:04:12:b1:a2 successfully [ 2461.927965] mwifiex_sdio mmc0:0001:1: CMD_RESP: cmd 0x23f error, result=0x2 [ 2461.953056] mwifiex_sdio mmc0:0001:1: CMD_RESP: cmd 0x23f error, result=0x2 [ 2464.936578] mwifiex_sdio mmc0:0001:1: info: successfully disconnected from 34:08:04:12:b1:a2: reason code 2 Has anyone used linux-firmware-sd8801 on kernel 5.10 or am I the only one in trouble?
