Let me have a couple of question on developing DRAM test program on Jetson TX1.
- nvtboot source code (1st bootloader : Memory initialization with cfg file)
- Solution to set the Memory frequency to 800MHz at the bootloader(uboot)
- in the nvtboot : Do training at 408->665->800->1065->1331->1600Mz, finally set to 800MHz
-> how to set Memory frequency to 1600MHz(nvtboot code or uboot code)
S/W Engineer would like to test DRAM at uboot stage not kernel to have more free memory to be tested. I would like to have source code of nvtboot for manupulating the DRAM CLK, AC timing and etc after uboot. I only have binary code for nvtboot.
- Solution to change Memory VDD1/VDD2/VDDDQ in the bootloader(uboot)
Can I get H/W or S/W solution to change DRAM voltage(VDD1/VDD2/VDDQ) at boot stage?
I appreciate your help.
