Hi,
We are using imx6Q sabresd platform for our development with Linux
3.10.17_1.0.0-GA BSP.
We have installed the meta-tool chain in our 64bit Host PC and 32
bit Host PC using below steps.
$bitbake meta-toolchain
$sudo sh
tmp/deploy/sdk/poky-eglibc-x86_64-arm-toolchain-<version>.sh
The u-boot source code is compiled in 32bit host PC and with this
u-boot.imx binary, the target board is booted.
At u-boot level, the command "bdinfo" displays below information.
arch_number = 0x0000112D
boot_params
= 0x10000100
DRAM
bank = 0x00000000
->
start = 0x10000000
->
size = 0x40000000
eth0name
= FEC
ethaddr
= 00:01:02:03:04:05
current
eth = FEC
ip_addr
= <NULL>
baudrate
= 115200 bps
TLB
addr = 0x4FFF0000
relocaddr
= 0x4FF68000
reloc off =
0x38768000
irq_sp
= 0x4F565F38
sp
start = 0x4F565F28
Then the u-boot source
code is compiled in 64bit host PC and with this u-boot.imx binary,
the target board is booted.
At u-boot level, the command "bdinfo" displays below information.
arch_number = 0x0000112D
boot_params
= 0x10000100
DRAM
bank = 0x00000000
->
start = 0x10000000
->
size = 0x40000000
eth0name
= FEC
ethaddr
= 00:01:02:03:04:05
current
eth = FEC
ip_addr
= <NULL>
baudrate
= 115200 bps
TLB
addr = 0x4FFF0000
relocaddr
= 0x4FF66000
reloc off =
0x38766000
irq_sp
= 0x4F563F38
sp
start = 0x4F563F28
We would like to know, why the "relocaddr
& reloc off "(as highlighted above) are different?
since the source codes are same and compiled in different host PC
(64bit & 32bit).
In addition, we checked the u-boot.imx binary file size. We could
see the difference in the file size as below
u-boot.imx(compiled in 32bit host PC) - 313644 bytes
u-boot.imx(compiled in 64bit host PC) -
318780 bytes
Thank You,
Regards,
Ansari
