rv1126-rv1109-分区修改_rv1126 media分区

因为一些需求做一点分区修改尝试       

因为rv1126分区很难受

就是由parameter-buildroot-fit.txt生成最后parameter.txt

于是我手动修改了parameter.txt

发现这个是分区列表,可以在uboot里看到

修改如下

FIRMWARE_VER: 8.1
MACHINE_MODEL: RV1126
MACHINE_ID: 007
MANUFACTURER: RV1126
MAGIC: 0x5041524B
ATAG: 0x00200800
MACHINE: 0xffffffff
CHECK_MASK: 0x80
PWR_HLD: 0,0,A,0,1
TYPE: GPT
CMDLINE: mtdparts=rk29xxnand:
0x00002000@0x00004000(misc),
0x00010000@0x00006000(boot),
0x00002000@0x00016000(uboot),
0x00014000@0x00018000(recovery),
0x00200000@0x0002C000(rootfs),
0x00010000@0x0022C000(backup),
0x00060000@0x0023C000(oem),
0x00200000@0x0029C000(userdata),
-@0x0049C000(media:grow)
uuid:rootfs=614e0000-0000-4b53-8000-1d28000054a9

开机也能正常运行,就说明改这里是可行的,

为什么呢?

因为之前有修改过,读分区的时候是通过分区的名字来获取分区里面的内容
