k2 ddr3

1：板子使用的tci6638k2h的evm板，内存条为三星m471b5773dh0-ch9，使用k2_STM的例子，按照内存条的参数进行配置，在EVM板上多次操作无法读写

如下

[C66xx_0] Initialize DSP main clock = 122.88MHz/4×39 = 1198MHz
DDR3A initialization
Initialize DDR data rate = 100.000×40/3= 1333.3 MTS
wait DDR3 PHY status in PGSR0 register timeout!
DDR PHY status PGSR0=0xb1e001ff.
DDR PHY Write Bit Deskew is NOT done!
DDR PHY Read Eye Training is NOT done!
DDR PHY Write Eye Training is NOT done!

Initialize DSP main clock = 122.88MHz/4×39 = 1198MHz
DDR3A initialization
Initialize DDR data rate = 100.000×40/2= 2000.0 MTS
wait DDR3 PHY status in PGSR0 register timeout!
DDR PHY status PGSR0=0xb1e001ff.
DDR PHY Write Bit Deskew is NOT done!
DDR PHY Read Eye Training is NOT done!
DDR PHY Write Eye Training is NOT done!

Initialize DSP main clock = 122.88MHz/4×39 = 1198MHz
DDR3A initialization
Initialize DDR data rate = 100.000×16/2= 800.0 MTS
wait DDR3 PHY status in PGSR0 register timeout!
DDR PHY status PGSR0=0xb1e001ff.
DDR PHY Write Bit Deskew is NOT done!
DDR PHY Read Eye Training is NOT done!
DDR PHY Write Eye Training is NOT done!
2：采用uboot版本中读取内存条参数进行配置的，也对这内存条区域无法读写，查出 PGSR0=0xb1e001ff.

请问是否有dsp的ddr3参数配置自动测试软件？不然在自己板子上没内存条用

Allen35065：

DDR3需要根据参数自行配制，还有必须要支持1.5V的DDR3颗粒才可以。
