@Bones558 @alexc I noticed that several USB-C drivers are missing in the 6.6 kernel. While the Makefile and Kconfig files are present, they have changed significantly. In the 5.15 BSP, the bsp/drivers/usb/typec/tcpm directory contains tcpci_et7304.c and tcpci_husb311.c, but in 6.6, this directory is empty. 6.6: bsp/drivers/usb/typec/tcpm$ ls Kconfig Makefile 5.15: bsp/drivers/usb/typec/tcpm$ ls Kconfig Makefile tcpci_et7304.c tcpci_husb311.c

@Nick A @Bones558 Hi there, I am not sure if that's definitely due to DRM heap. But I fixed that driver and it could be built now. I didn't know if USB C DP works or not before but it is working now (on a USB C monitor, maybe needs a few re-plug). I opened a PR on Radxa allwinner-bsp github (https://github.com/radxa/allwinner-bsp/pull/11), you can also test it out.

Excellent, thanks. One more thing. I just reloaded the x98h image. When I previously loaded this image, I didn't check dmesg like I did with the other images. They had no mention of Wifi at all but this one does. It seems to start enabling wifi but then fails here rwnx_load_firmware :firmware path = /lib/firmware/aic8800_sdio/fw_patch_table_u03.bin rwnx_load_firmware: fw_patch_table_u03.bin file failed to open wrong size of firmware file aicbt_patch_table_alloc fail edit: So lib/firmware/aic8800_sdio/fw_patch_table_u03.bin does not exist which probably explains that error. I'll see if I can get my hands on that file and see if that fixes things before I worry about compiling/decompiling stuff.

@BoringName Looks right. You can decompile the dtb into a dts.. edit the dts and compile it again. You will find it in the /boot directory. dtc -I dtb -O dts -o mainline_edit.dts your_mainline_file.dtb dtc -I dts -O dtb -o modified_mainline.dtb mainline_edit.dts

Ok, just so I'm following you correctly. This line in my DTS dump bt_rst_n = <0x23 0x06 0x13 0x01>; In decimal is <35 6 19 1> In the patch you linked the line above should be matched to these values at line 293? reset-gpios = <&pio 6 13 GPIO_ACTIVE_LOW>; /* PH13 bt_rst_n */ So I should change this to reset-gpios = <&pio 6 19 GPIO_ACTIVE_HIGH>; /* PH13 bt_rst_n */ Repeat for all the other values to match the DTS dump then build the image? Is there a way to set these values at the command line without having to build an image? edit: Actually my high low flag is 0x13 which is 0001 0011. This is read from right to left isn't it? So Bit 0 is actually a 1 which means in the example above I should set it to the following? reset-gpios = <&pio 6 19 GPIO_ACTIVE_LOW>; /* PH13 bt_rst_n */ Sorry I'm probably getting in a little over my head....
