Hi,
Our platform is based T1040 Reference platform, we are trying to add Power On Self Test support in u-boot.
Seems like this is disabled for T1040RDB,
We see that CONFIG_POST is not allowed as cpu_init.c throws error "POST memory test cannot be enabled with TDM"
I tried to change T104xRDB.h to include the CONFIG_POST CONFIG_SYS_POST_MEMORY.
What are the options for us for DDR test from u-boot?
Thanks
Vijay
Use the "mtest" command from u-boot. See the following page:

Have a great day,
Pavel Chubakov

Also looking at the bdinfo.
memstart = 0x00000000
memsize = 0x100000000
flashstart = 0xE8000000
flashsize = 0x10000000
flashoffset = 0x00000000
sramstart = 0x00000000
sramsize = 0x00000000
immr_base = 0xFE000000
bootflags = 0x00000000
intfreq = 1400 MHz
busfreq = 600 MHz
addressing = 36-bit
ethaddr = 68:05:ca:44:0d:03
IP addr = 192.168.0.56
baudrate = 115200 bps
relocaddr = 0x7FEF0000
I will never be able to use mtest for the range 0x00000000 - 0x100000000,
as uboot gets relocated at the relocation address and Flash is memory mapped from 0xE8000000.
Can some one give us what is the ideal approach?
Thanks
I have tried this, this seems slower. So was looking for POST as this is fast and we can run this every time boot the system.
Thanks
