arclight Posted June 9, 2022 Share Posted June 9, 2022 hello armbian developers recently i have tried to built my own kernel from linus' kernel tree(5.18.1). the build config i use cames from armbian 22.05 bullseye(5.15.43-sunxi) /boot/config-5.15.43-sunxi ,without any changes. the kernel was ok to boot,so i plan to add xr819 support for it,but after days of work,it seems not as easy as i thought. the driver ive tried is from here(https://github.com/karabek/xradio),but it cant detect chip's hardware revision: [ 13.036884] xradio: XR819 device discovered [ 13.038054] xradio_wlan mmc1:0001:1: no mac address provided, using random [ 13.064445] xradio ERR: FWIO: Unknown hardware: -1. [ 13.064547] xradio ERR: BH: bh thread exiting [ 13.064893] xradio PM-DEV: xradio_pm_release but the stock armbian image works well(5.15.43-sunxi). so i have added a printk to make config reg value visible: ret = xradio_reg_read_32(hw_priv, HIF_CONFIG_REG_ID, &val32); printk(KERN_WARNING "xradio_wlan: read config reg value: 0x%x\n",val32); if (ret < 0) { xr_printk(XRADIO_DBG_WARN, "FWIO: can't read config register, err=%d.\n", ret); return ret; } on 5.15.43: [ 11.737046] xradio: XR819 device discovered [ 11.737725] xradio_wlan mmc1:0001:1: no mac address provided, using random [ 11.739304] xradio_wlan: read config reg value: 0x4005600 [ 11.920160] xradio: hardware vers. 7.9 [ 11.920199] xradio: firmware vers. 8 (WSM), build 5258, api 1060, cap 0x0003 [ 11.920217] xradio: Config USE_EXTENSIONS on 5.18.1: [ 13.036884] xradio: XR819 device discovered [ 13.038054] xradio_wlan mmc1:0001:1: no mac address provided, using random [ 13.039290] xradio_wlan: read config reg value: 0x4 [ 13.064445] xradio ERR: FWIO: Unknown hardware: -1. [ 13.064547] xradio ERR: BH: bh thread exiting [ 13.064893] xradio PM-DEV: xradio_pm_release it seems xradio_reg_read_32 will call xradio_reg_read , and it calls __xradio_read ... last call sdio_memcpy_fromio , so maybe upstream have changed some implementation of sdio? 0 Quote Link to comment Share on other sites More sharing options...
