Hi,
So I found few things regarding your suggestions (BTW thanks for them)
when expanded to values the qspiboot is:
qspiboot=echo Copying Linux from QSPI flash to RAM... && sf probe 0 0 0 &&
sf read 0x2080000 0x100000 0x500000 && sf read 0x2000000 0x600000 0x20000
&& echo Copying ramdisk... && sf read 0x4000000 0x620000 0x5E0000 && bootm
0x2080000 0x4000000 0x2000000
>From this I get that in flash I should have kernel on address 0x100000,
which I don't supply while merging with bootgen. Is this correct asumption?
after executing:
zynq-uboot> sf probe 0 0 0
SF: Detected S25FL128S_64K with page size 512 Bytes, erase size 128 KiB,
total 32 MiB
zynq-uboot> sf read 0x2080000 0x620000 0x500000
SF: 5242880 bytes @ 0x620000 Read: OK
zynq-uboot> iminfo 0x2080000
## Checking Image at 02080000 ...
Legacy image found
Image Name: core-image-minimal-mod-initramfs
Image Type: ARM Linux RAMDisk Image (gzip compressed)
Data Size: 2220303 Bytes = 2.1 MiB
Load Address: 00000000
Entry Point: 00000000
Verifying Checksum ... OK
zynq-uboot>
i get from this that what I get while building is just the ramdisk, and not
the uImage with kernel and ramdisk, correct?
If my asumptions are correct, what should I do to get yocto to build and
image of kernel with ramdisk?
