STM32MP1驱动加载问题如何解决？

142 Linux

问答对人有帮助，内容完整，我也想知道答案 0 我试图让 VL53L3CX 的 linux 驱动程序在 STM32MP157C-DK2 上运行。已经解决了一些问题：通过更正函数名称（timeval => __kernel_old_timeval 和 i2c_new_device => i2c_new_client_device，仅此而已）使其与新内核一起使用，使其使用 bitbake 进行编译并更改使用的 gpio 引脚以在我的板上使用它而不是 raspberry pi . 现在编译驱动程序。我还使用i2cdetect -y 1验证了 VL53L3CX 已连接并且可以在地址 29 处检测到。但是我在尝试加载内核模块时遇到错误： modprobe stmvl53lx 结果： [ 545.281289] stmvl53lx_parse_tree: Unable to find boot-reg -22 41 [ 545.281366] get_pwren: pwren gpio disable [ 545.291058] cci_read: i2c_transfer :-6, @29 index 0xe5 len 1 [ 545.299320] stmvl53lx_reset_release_i2c: boot fail with error -13 [ 545.299333] reset_release: reset release fail rc=-5 [ 545.310389] ------------[ cut here ]------------ [ 545.314976] WARNING: CPU: 0 PID: 1105 at drivers/regulator/core.c:2123 _regulator_put.part.0+0x164/0x16c [ 545.324645] Modules linked in: stmvl53lx(O+) usb_f_rndis aes_arm u_ether aes_generic cmac algif_skcipher libcomposite snd_soc_audio_graph_card snd_soc_simple_card_utils brcmfmac stusb160x typec cfg80211 galcore(O) brcmutil stm32_crc32] [ 545.377256] CPU: 0 PID: 1105 Comm: modprobe Tainted: G W O 5.10.10 #1 [ 545.384646] Hardware name: STM32 (Device Tree Support) [ 545.389818] [] (unwind_backtrace) from [] (show_stack+0x10/0x14) [ 545.397547] [] (show_stack) from [] (dump_stack+0xb8/0xcc) [ 545.404774] [] (dump_stack) from [] (__warn+0xec/0x104) [ 545.411739] [] (__warn) from [] (warn_slowpath_fmt+0x64/0xc4) [ 545.419234] [] (warn_slowpath_fmt) from [] (_regulator_put.part.0+0x164/0x16c) [ 545.428198] [] (_regulator_put.part.0) from [] (regulator_put+0x28/0x38) [ 545.436771] [] (regulator_put) from [] (stmvl53lx_release_gpios+0x2c/0xc8 [stmvl53lx]) [ 545.446451] [] (stmvl53lx_release_gpios [stmvl53lx]) from [] (stmvl53lx_probe+0xb4/0xd4 [stmvl53lx]) [ 545.457263] [] (stmvl53lx_probe [stmvl53lx]) from [] (i2c_device_probe+0x278/0x2b0) [ 545.466611] [] (i2c_device_probe) from [] (really_probe+0x208/0x4f0) [ 545.474705] [] (really_probe) from [] (driver_probe_device+0x78/0x16c) [ 545.482976] [] (driver_probe_device) from [] (device_driver_attach+0x58/0x60) [ 545.491859] [] (device_driver_attach) from [] (__driver_attach+0xb4/0x154) [ 545.500483] [] (__driver_attach) from [] (bus_for_each_dev+0x78/0xc0) [ 545.508673] [] (bus_for_each_dev) from [] (bus_add_driver+0x170/0x20c) [ 545.516944] [] (bus_add_driver) from [] (driver_register+0x74/0x108) [ 545.525045] [] (driver_register) from [] (i2c_register_driver+0x3c/0xac) [ 545.533560] [] (i2c_register_driver) from [] (stmvl53lx_init_i2c+0x34/0x108 [stmvl53lx]) [ 545.543397] [] (stmvl53lx_init_i2c [stmvl53lx]) from [] (do_one_initcall+0x58/0x2bc) [ 545.552835] [] (do_one_initcall) from [] (do_init_module+0x60/0x258) [ 545.560933] [] (do_init_module) from [] (load_module+0x1434/0x1788) [ 545.568945] [] (load_module) from [] (sys_finit_module+0xd4/0x130) [ 545.576872] [] (sys_finit_module) from [] (ret_fast_syscall+0x0/0x54) [ 545.585050] Exception stack(0xcc0a5fa8 to 0xcc0a5ff0) [ 545.590109] 5fa0: 00000000 00000000 00000003 0002270c 00000000 00040000 [ 545.598297] 5fc0: 00000000 00000000 00000000 0000017b 00034220 00000000 00000000 00000000 [ 545.606482] 5fe0: beb06890 beb06880 0001b3c9 410c8bb2 [ 545.611777] ---[ end trace c531c4ede0070016 ]--- [ 545.616597] stmvl53lx: probe of 1-0029 failed with error -1 有没有人对我的研究有帮助的建议？该错误从何而来？ 0

答案对人有帮助，有参考价值 0 _regulator_put中的WARNING信息是由stmvl53lx_setup失败时调用的stmvl53lx_release_gpios引起的（在stmvl53lx_probe中）。但在此之前，VL53LX_WaitDeviceBooted 已经返回错误，因为芯片在复位后没有成功启动。 [ 545.299320] stmvl53lx_reset_release_i2c: boot fail with error -13 错误-13 表示 VL53LX_ERROR_CONTROL_INTERFACE，这是从 IO 函数报告的错误。您能否分享与 stmvl53lx 相关的设备树部分（尤其是 xsdn-gpio 引脚）？你认为你需要配置 boot-reg 吗？
