- Around line 1-2: Update the board description comment in the nanopi6-series
configuration to state the RK3588S SoC, core count, RAM options, connectivity,
storage, and special hardware features. Update BOARD_NAME to include the NanoPi
M6V2 model while preserving the existing R6S, R6C, and M6 names.
- Around line 9-10: Update the KERNEL_TARGET and KERNEL_TEST_TARGET values in
the NanoPi 6 series board configuration to remove the vendor target unless the
vendor kernel tree also provides the requested rockchip/rk3588s-nanopi-m6v2.dtb.
Preserve the current and edge targets, and ensure vendor images cannot be
selected without the matching M6V2 device tree.

to check the return status of each control-FDT fixup, including
do_fixup_by_path(), and ensure the FDT has sufficient writable padding before

rk3588s-nanopi-r6s.dtb fallback as rk_board_late_init when get_board_model()
returns no model, allowing that FIT configuration to match instead of returning
-EINVAL for every option.
- Around line 186-203: Update spl_board_fixup_fdt() to check and handle the
return value of each do_fixup_by_path() call, including the possible
FDT_ERR_NOSPACE failure. Restrict the MMC/SPI status fixups to the M6 board,
since R6S and R6C do not share the affected pins; also ensure
board_fit_config_name_match() selects the appropriate SPI device tree for any
supported SPI-boot path.
- Around line 331-336: Add CONFIG_SPI_FLASH_ZBIT=y alongside the other SPI flash
vendor options in the defconfig, ensuring the Zbit vendor table is explicitly
enabled in addition to SFDP support.

Complete the interactive board description and board name.
Line 1 does not describe the hardware features required for board selection.
Line 2 omits the supported NanoPi M6V2 model.
Add an accurate hardware description with the SoC, core count, RAM options, connectivity, storage, and special features. Add M6V2 to BOARD_NAME.
Based on learnings: the first-line board comment is an interactive hardware description and must state SoC model, core count, RAM options, connectivity, storage, and special features.

@EvilOlaf, verified. M6V2 is the NanoPi M6 v2 board variant. This shared configuration supports it through the m6v2 runtime model path.
The first-line description correctly identifies this as a common image. The single-board hardware-description rule does not apply here. I am withdrawing the finding.

Learning: In `armbian/build`, a shared multi-purpose board configuration such as `config/boards/nanopi6-series.conf` can use a common-image description instead of the single-board hardware description normally required in the first comment line. The single-board description requirement does not apply to this type of shared image.

Learning: Enforce that the first line comment in Armbian board configuration files (e.g., config/boards/*.conf, and related boards files with extensions like *.csc, *.wip) contains a dedicated hardware feature description, not a description of what the file generates. The comment must specify: SoC model, core count, RAM options, and key features (connectivity options, storage interfaces, special features). This text is used during interactive compilation, so accuracy and completeness matter. For any new board config file, flag if the first-line comment is not descriptive of the hardware (e.g., prefer '# Qualcomm QCS8250 octa core 4GB-16GB eMMC GBE USB3 WiFi BT' over '# Generate kernel and rootfs image...').

Timestamp: 2025-09-18T03:36:17.862Z
Learning: In Armbian board configuration files (regardless of file extension), the standard pattern is to have only one line as a comment describing the board hardware specifications. This single-line description typically includes the SoC model, core count, RAM options, and key features like connectivity options, storage interfaces, and special features. The file extensions indicate board support status: .conf (standard support), .csc (community supported), .eos (end of support), .tvb (tvbox), .wip (work in progress).

ah well, there is indeed an m6v2. But yeah, it is up to the author if this is actually also supported or not
Contributor

@EvilOlaf, agreed. The M6V2 board exists, but inclusion in this common image is an author decision. The implementation defines the supported set. No further action is needed for this withdrawn finding.

Handle control-FDT fixup failures
fdtdec_setup() initializes gd->fdt_blob before this hook, and dm_init() builds the live tree afterward. However, it does not guarantee spare writable FDT capacity. Check the do_fixup_by_path() results and ensure sufficient padding before DM scans the tree; otherwise -FDT_ERR_NOSPACE is ignored.

Check the do_fixup_by_path() return values, and confirm the R6S/R6C SPI-boot path.
Two points on this hook.
- Neither call is checked.
do_fixup_by_path()callsfdt_setprop(), which can return-FDT_ERR_NOSPACE. The value length changes between 5 bytes ("okay") and 9 bytes ("disabled"), so the blob can grow. A silent failure leaves both controllers in their DT default state, and DM then probes the wrong one. - The hook applies to every board in the series, but only M6 shares the eMMC and FSPI-M0 pins. If an R6S or R6C boots from SPI, this hook disables
mmc@fe2e0000on hardware that has no pin conflict.board_fit_config_name_match()at Line 246 also selects the SPI device tree only for M6, so an SPI-booted R6S runs U-Boot proper with&sfcdisabled and cannot rewrite its own SPI flash.
Restrict the fixup to the boards that need it, or document why the series-wide behavior is intended.
Proposed error handling
void spl_board_fixup_fdt(void)
{
void *blob = (void *)gd->fdt_blob;
bool from_spi = booted_from_spi();

Align the FIT fallback with the environment fallback.
rk_board_late_init() at Line 229 falls back to rk3588s-nanopi-r6s.dtb when detection fails. board_fit_config_name_match() returns -EINVAL for every configuration in the same case. SPL then finds no matching configuration and the board does not boot.
If the ADC read fails on a working board, the two functions must behave the same way.
Proposed fallback

{
const struct board_model *model = get_board_model();
const char *fit_name;

53-79: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Give the two ADC buttons distinct node names and key codes.
Both nodes are named
button-maskrom, and both reportKEY_VENDOR. The labels differ ("Maskrom" and "Recovery"), but labels are not exported as input event codes. Userspace therefore cannot tell the two buttons apart.Rename the second node and assign a distinct key code.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.adc-keys { compatible = "adc-keys"; io-channels = <&saradc 0>; io-channel-names = "buttons"; keyup-threshold-microvolt = <1800000>; poll-interval = <100>; button-maskrom { label = "Maskrom"; linux,code = <KEY_VENDOR>; press-threshold-microvolt = <1800>; }; }; adc-keys-1 { compatible = "adc-keys"; io-channels = <&saradc 1>; io-channel-names = "buttons"; keyup-threshold-microvolt = <1800000>; poll-interval = <100>; button-recovery { label = "Recovery"; linux,code = <KEY_SETUP>; press-threshold-microvolt = <1800>; }; };🤖 Prompt for AI Agents

Confirm the
vcc_3v3_sd_s0voltage constraints.The regulator is named
vcc_3v3_sd_s0and takes its input fromvcc_3v3_s3, but bothregulator-min-microvoltandregulator-max-microvoltare3000000.&sdmmcat Line 502 uses this rail asvmmc-supply, so the MMC core reports 3.0 V for the card supply.If the board rail is a 3.3 V load switch from
vcc_3v3_s3, set both values to3300000.Verify against the FriendlyElec schematic before you change the values.

There was a problem hiding this comment.
Nice. I wonder if keeping the old board files, with an include (eg similar to https://github.com/armbian/build/blob/main/config/boards/nanopct6-lts.conf) would help keep compatibility? (eg without this, the bsp-cli packages for the removed boards would disappear/be left in old version in apt repos).

Yes that makes sence. I will add them back for backward-compatbility. |

Description
This PR unifies NanoPi R6S, R6C and M6 images by distinguishing them using SARADC at uboot and SPL level. As well as, the PR also adds support for new M6V2 board. Also the DSI overlay of M6 is no longer enabled by default and it has to be enabled manually from armbian-config or armbianEnv.txt
To get images working with this way, old SPI images or uboot loaders stored in eMMC must be erased or updated as the bootrom order of SPI and eMMC is higher than SD card.
