It turned out that the issue was in my nand flash that was increased to 512MB. It's related to PEB blocks allocation of ubiattach. Increasing /userdata partition size in board config solved the issue and now i can remount rootfs and oem as read-only and use /userdata as my only rw region. Thanks for...

I think i'll be fine with rootfs of ubifs and userdata of ubifs. I can remount my rootfs to read-only during boot. However, in spi nand image, it does not mount ubi5_0 block to /userdata successfully. I use your official image and during boot, when S20linkmount tries to mount ubi5_0 as /userdata it ...

Ok, got you. Will try to fix it by myself and share with you if something will work out!

Everything worked out after following your last recommendations, thanks a lot! Now i can finally enjoy my tty console at UART4_M1

Thank you! UPD: I changed following line in my BoardConfig: export RK_PARTITION_FS_TYPE_CFG=rootfs@IGNORE@erofs,oem@/oem@erofs,userdata@/userdata@ubifs Unfortunately the image i build after that doesn't boot and i have kernel panic Screenshot from 2025-05-23 11-46-56.png In uboot environment i have ...

Hi! I want to create a system image for spi-nand with ubifs where my rootfs partition will be read-only. However, i need a little amount of rw space inside my filesystem. Is it possible to create a dedicated physical partition on a nand flash for that purpose? I can certainly remount nand partitions...

Aight, thanks! I've read this post already. The issue is seem to be related to the inability of gdb to process modern c++ code with auto function arguments. Thats quite sad, but at least now i know what to expect

Hi! Recently i came across some issues while debugging my c++ applications that i cross-compile for my luckfox pico mini b. My setup is gdb from cross-toolchain: photo_2025-04-29_12-04-39.jpg and gdbserver from your buildroot sdk: photo_2025-04-29_12-07-52.jpg I use vscode IDE and have managed to se...

First, thanks you for your patience! Second, i need to clarify that im using luckfox pico mini b board. I've caught up with your previous post update. AFAIK i need to change stdout-path not in v1106-luckfox.dts, but in rv1106-evb.dts (as it's chosen by Uboot defconfig). I've changed this dts node an...

It behaves really weird. I did all the required changes from your previous post, nothing except that (modified ddrbin, changed fiq-debugger node in u-boot dts and added uart4 and fiq-debugger changes in final kernel dts). During the boot, i still reveive debugging messages on UART2 and they disappea...
