firmware_merger read setting.ini to get partition info and create firmware.firmware_merger can generate
|
three kinds of firmware(1.flat rk firmware 2.flat gpt firmware 3.compact gpt firmware).flat firmware can be
|
directly written into flash by 'wl'command.Compact firmware can only be written by productiontool. when SPL
|
is rk miniloader,firmware use flat rk format.when SPL is u-boot,firmware use flat gpt.
|
|
follow us to config settting.ini:
|
1.set format of firmware
|
Gpt_Enable= /*flat rk firmware*/
|
Gpt_Enable=0 /*flat gpt firmware*/
|
Gpt_Enable=1 /*compact gpt firmware*/
|
|
2.backup header of firmware or not
|
Backup_Partition_Enable=1 /*backup firmware header*/
|
Backup_Partition_Enable= /*default,no backup firmware header,when you don't know flash size,no backup*/
|
|
3.idblock partition (must be first partition)
|
Name=IDBlock /*partition name,fixed 'IDBlock'*/
|
Type=0x2 /*partition type,fixed=2*/
|
PartOffset=0x40 /*partition offset,fixed=0x40*/
|
PartSize=0x400 /*partition size,must be smaller than 2M*/
|
Flag= /*partition flag,default value*/
|
File=Image/FlashData.bin,Image/FlashBoot.bin /*ddr_init.bin,loader.bin*/
|
|
4.layout other partition sequentially,four case to config
|
a.written partition file and fill up to partition size
|
Flag=
|
File=partition file
|
|
b.partition be filled up to partition size
|
Flag=0x2
|
File=/*do not set*/
|
|
c.skip,none of data be written to partition
|
Flag=0x1
|
File=/*do not set*/
|
|
d.last partition,partition size be set at runtime,alloc all of remain flash to it
|
Flag=0x4
|
File=/*set file as required*/
|
|
5.fix partition uuid
|
a.add Type_Guid=UuidKeyName into partition section
|
b.add uuid item into PARTITION_TYPE_GUID section
|
example:
|
[userPart1]
|
Name=rootfs
|
Type_Guid=rootfs_uuid
|
[PARTITION_TYPE_GUID]
|
rootfs_uuid=00000000-0000-0000-0000-000000000000
