Hi, trying to install a char driver without any driver framework. The only thing I can not install is getting the Interrupt through to the interrupt servce routine err = request_irq(irq, handler, // IRQF_TRIGGER_RISING, IRQF_TRIGGER_HIGH, "can4linux", &can_minors[minor]); irq is the Interrupt number of the CAN controller, it is fixed in the A20 to 58. I do get no error messages, but the isr is not called. What I am missing? Greetings Heinz By the way, it worked an Bananian 3.x

Igor, in https://armbian.atlassian.net/browse/AR I can see you marked it as solved. Did now expect that we have new kernel-headers, but apt-get update and apt-get upgrade does not show a new one? May be it is not related but I can not get interrupt number 58 (CAN module) working. I'm sure all these tasks are above my skills, but when finished may small project, I'll have a look at it.

You know. your kid and we, are thankful

Thanks, and take care of your family.

Hi, have the same problem with compiling the can4linux driver. Why does someone suggest to remove the last line of the linker script module.lds ? sudo sh -c "sed '$ d' it should include something for sure, may be the .plt section. #include does not work, so I added the content of ./linux-headers-5.10.4-sunxi/arch/arm/include/asm/module.lds.h now I can load the module, but is may be not correct

look at the text: "behing" should be "behind"

I read on the forum: "Update boot loader to latest version - armbian-config -> system -> install/update boot loader ... and try again." and I did. I also removed power, reconnected the cables, and now the result is different: I have now the device /dev/sda available. Hopefully, all is good now.

Today I updated my BananaPI M1 board, replaced the Bananian OS with Armbian Armbian_20.05.4_Bananapi_focal_current_5.4.45.img. I'm not getting the SATA with connected 1TB WD10JFCX working. The HD worked before with the Bananien kernel 3.4.x What can I do, how can I test, how can i get more information about the reason? The board is powered via the Micro USB and armbianmonitor reports DC-IN voltage > 5V

only added the second last printf, and of course the variable initialisation

did read (most of) this thread, Thanks. I just started using Armbian so everything is new.

I found the CAN device driver sources in sun7i_can.c - CAN bus controller driver for sun7i to configure the gpio pins for the special case of acting as TX and RX for CAN, the following function calls are used: sw_gpio_setcfg(GPIOA(16), 3); I try to use this code to implement the can4linux module an a BananaPi M2-Berry using Armbian stretch but are not able to find any prototype of such a function sw_gpio_setcfg(); nor the definitions of the gpio ports like GPIOA. What ist the correct way of accessing the gpio ports from within the kernel? Thanks for helping.

The headline still shows "Armbian 5.75 stable"
