TDA2PXEVM: after early boot，late attach may be fail

Hi Shravan,
1.We develop product start with version 3.4 and merged the version 3.5 code later .
2.Yes,we are building both IPU-1 and IPU-2. We tried to change early-boot-load.sh script for adding ipu-1 binary,after that it would login into shell fail. What we need to change the DTB ? Below is the dra76-evm-infoadas.dts.Could help to have a look?

Thanks
Terence Xia

Hello,
I tried to adding dra7-ipu1-fw.lzop in boot partition.There is a problem that the system crash. We suspect the reasons may be the modified memory address of ipu1 is unmatch,but I’m not sure.
I tried to change “ti_components/os_tools/linux/u-boot/u-boot/include/configs/ti_omap5_common.h”, it has a line “#define IPU1_LOAD_ADDR (0xb0000000)”,and I changed the line to “#define IPU1_LOAD_ADDR (0x9A000000)” for matching with IPU1_START_ADDR which defined in mem_segment_definition_linux.xs , and also match with &ipu1_cma_pool address defined in dra76-evm-infoadas.dts .But it does not work ,system still crash. Does IPU1_LOAD_ADDR is equal to IPU1_START_ADDR?

Regards
Terence
