Other Parts Discussed in Thread: TMDS64EVM, SYSCONFIG
Tool/software:
Hi,
In TI default board TMDS64EVM, we have DDR type MT40A1G16KD-062E.
I am using the sysconfig tool to config ddr parameter. It was working fine.
In our customised board, we are using DDR MT40A512M16TB-062E. It was not working.
1. What is the minimum requirement for hardware? We just check the clock behavior between two boards, it is the same behavior. eg: VTT is 0.6 volts.
2. What is the minimum requirement for software?
eg:
a. do we need to change board_ddrReginit.h?
b. we don't need to pull up VTT, since hardware guy put it to 0.6
<code>
/* Pull VTT high */
HW_WR_REG32_RAW (CSL_GPIO0_BASE + GPIO_SET_DATA01, (1U << 12U));
gpio_dirVal = HW_RD_REG32_RAW(CSL_GPIO0_BASE + GPIO_DIR01);
HW_WR_REG32_RAW(CSL_GPIO0_BASE + GPIO_DIR01, gpio_dirVal | (1U << 12U));
</code>
Thanks.
