I was rechecked that openvfd works and get its config openvfd dtbo overlay fragment (decompiled on running system) It works, driver loaded and userspace software shows me current time on LED (some segments shows wrong, i think it result of wrong chars config) tm16xx: I've tried many values for GPIO line config, GPIO_ACTIVE_LOW (1), GPIO_ACTIVE_HIGH | GPIO_OPEN_DRAIN (6), GPIO_ACTIVE_HIGH (0), GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN (7). It was no result at all, driver still says that cannot init controller. Also i was tried drivers fd6551, fd655 with different GPIO lines config. No success. I was rechecked LED controller chip on board, it is really FD6551. tm16xx dtbo overlay fragment (decompiled on running system) I have no ideas what goes wrong. When i was configure openvfd device tree, pointing gpio chip as &gpio was not works. Only pointing as "0300b000.pinctrl" was successful. Maybe, its important... Maybe, some features/conflicts at controller init needs debugging

Yes, i've tried pin flag 0 and 1 -- no effect

Thanks!! I had compiled tm16xx, attach dtb overlay, and trying to load modules. dmesg: my old dts overlay for openvfd: new dts overlay: Configs looks equals in hardware config, but driver not loading...

Hello! I have a strange behavior at compiling As i knew, fwnode_for_each_available_child_node_scoped was committed to kernel at 2024 year.. Thats my kernel Any ideas?

Yes, i know, but i think this is mostly UBoot DRAM controller parameters problem. May be someone have any suggestions about it...

Hello! I have a T95MAX ver 3 board with H616 / AXP313 / 4Gb RAM. I've compiled an Armbian from Nick repo (https://github.com/NickAlilovic/build), branch v20251014 for Transpeed-8k618 with a little defconfig patch for TOC0 and DCDC3 voltage = 1.5V (extracted from Android native image DTB). CONFIG_AXP_DCDC3_VOLT=1500 CONFIG_SPL_IMAGE_TYPE_SUNXI_TOC0=y Image booting ok, but first UBoot stage found 4Gb and second stage found only 2Gb. Someone have any ideas for make 2nd stage and kernel detect full memory?
