Tool/software:
Hi Ti Expert,
We have custom beard referenced from the EVK. i am trying to boot from the SD card
after below attached log board stuck
our DDR is different from the EVK. In EVK DDR is dual rank and in our custom board we have single rank.
we followed the below thread to change the DDR configuration. but still we are not able to boot from the SD card.
AM62A7: RAM size configuration in the u-boot dts file
In our case DDR size is same as used in EVK (4GB). The only difference is we have DDR single rank.
I have made below changes in EVK u-boot source for changed ddr from dual rank to single rank.
Previous setting k3-am62a7-sk.dts
memory@80000000 {
device_type = "memory";
/* 4G RAM */
reg = <0x00000000 0x80000000 0x00000000 0x80000000>,
<0x00000008 0x80000000 0x00000000 0x80000000>;
};
New setting k3-am62a7-sk.dts
memory@80000000 {
device_type = "memory";
/* 4G RAM */
reg = <0x00000000 0x80000000 0x00000000 0x100000000>;
};
changed CONFIG_NR_DRAM_BANKS=2 to CONFIG_NR_DRAM_BANKS=1 also
setting in k3-am62a7-r5-sk.dts
memory@80000000 {
device_type = "memory";
- /* 4G RAM */
- reg = <0x00000000 0x80000000 0x00000000 0x80000000>,
- <0x00000008 0x80000000 0x00000000 0x80000000>;
+ /* 4G RAM */
+ reg = <0x00000000 0x80000000 0x00000000 0x100000000>;
bootph-pre-ram;
};
is there any other changes required ?
Is these setting that i have done correct?
Thanks
