<DC-IRC> [Discord] <xmort> I can do that, but ... I would really appreciate it if I could always rescue it via SD card, and I don't see any reason not to prefer SD card to eMMC
<DC-IRC> [Discord] <monkablyat> true just know about the devices i have like rock 5b or khadas edge 2 and they boot from sd if armbian is already flashed to emmc
<DC-IRC> [Discord] <amazingfate> check devicetree and source code of uboot
<DC-IRC> [Discord] <xmort> I don't understand how to use mask ROM to unbrick the r6c.. the docs are here: https://wiki.friendlyelec.com/wiki/index.php/NanoPi_R6C#Enter_Maskrom_Mode_to_Erase_the_Storage_Device_2 but I don't know what " Connect NanoPi-R6C to the computer using a USB data cable" means
<DC-IRC> [Discord] <xmort> ah you use a USB A<->A cable, connecting to the USB 3 connector
<DC-IRC> [Discord] <xmort> Luckily I have an A<->A cable laying around from having dealt with other rockchip boards 😅

<DC-IRC> [Discord] <runaway97> hmm no
<DC-IRC> [Discord] <runaway97> R6C has USB-C ports for that, just like most other SBCs
<DC-IRC> [Discord] <runaway97> only rock 5a as far as i know needs usb-a for maskrom
<DC-IRC> [Discord] <runaway97> R6C has an USB-C port for that, just like most other SBCs
<DC-IRC> [Discord] <mecoblock> If R6 is like R5 from friendlyelec then I got the best results taking it off power for like 30 sec and then doing the maskrom button boot
<DC-IRC> [Discord] <mecoblock> Sometimes it takes a few tries especially if it has been connected to power the whole time
<DC-IRC> [Discord] <beohoff3174> Hey is there an easy way to debug this in the kernel other than putting print statements in the driver code?

<DC-IRC> [Discord] <beohoff3174> FFMPEG is throwing/causing kernel exceptions with the HDMIRX module in 6.10
<DC-IRC> [Discord] <beohoff3174> I'm thinking about dropping into calling the v4l API
<DC-IRC> [Discord] <beohoff3174> I'm thinking about dropping into calling the v4l API, to see if it's an issue with ffmpeg or if it's the module
<DC-IRC> [Discord] <beohoff3174> If I'm reading the call stack correctly (and not upside down), it looks like it's breaking in here `vb2_core_reqbufs`:
<DC-IRC> [Discord] <beohoff3174> I'm getting this with both the C++ code I have and also using the command line ffmpeg
<DC-IRC> [Discord] <beohoff3174> Follow up question, is there a way toggle debug mode in linux while building armbian?
<DC-IRC> [Discord] <beohoff3174> Looks like you can toggle debug mode in linux using the "show a kernel config menu"
