2026-07-28实刷Loader rk356x_spl_loader_v1.25.114.bin，SHA256 d7db6f39d0b0dd2b5d12e3944d670b2e8ad7ba42029b249f03d9c8ff71bf9bba，来自radxa/rkbin develop-v2026.01，DDR1560 v1.25/SPL1.14。v1.21.113有较多eMMC写入与SPI恢复实证；MiniLoaderAll SHA256 512211c93043cf08368e42c0566afa818078d067f506a9f686396aa0fd3315d2，DDR1.23/SPL1.14，芯片与FlashInfo检测成功。Loader失败后断电重新MaskROM再测，脏状态出现过DDR错误。

Loader仅为RAM下载阶段组件，与系统镜像U-Boot分开。三种Loader的usbplug相同（98708字节v1.17）。条目名截断20个UTF16字符，真实版本应检查payload ASCII；boot_merger时间戳和CRC可改变整包哈希，应比payload。来源证据见 evidence/loader-provenance.txt。
|
||
常规下载镜像：Loader地址0xCCCCCCCC；Image选择EMMC地址0、解压后的raw .img而非.img.xz；勾选对应两行及强制按地址写。执行前核实EMMC约238592MB，避免默认SPINOR 32MB；结束断电拔USB并撤短接后通电。

2026-07-27误写SPI的RKNS曾位于0x10000/0x60000。历史恢复步骤为先确认32MiB SPI并备份sector0 length2048（1MiB），再擦除sector0 length65536（32MiB），随后切回EMMC。所有实际擦写仍需重新核实设备并取得授权。 |
