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
