LS1046A RCW

How to select rcw_1600_sdboot.rcw or rcw_1800_sdboot.rcw in frwy-ls1046a-ac code ?

[tian_shuliang]

I use lsdk1812, there are rcw_1600_sdboot.rcw and rcw_1800_sdboot.rcw. I want to know how to set different core freq.

Why ls1046a does not support 18000 MHZ frequency in lsdk1906 code?

LSDK 1812 doesn't support frwy-ls1046a.

Why ls1046a does not support 18000 MHZ frequency in lsdk1906 code?

For LS1046ARDB, 1800MHz frequency RCWs are provided in LSDK 1906 release.

For LS1046AFRWY, you could modify RCW configuration as the following to configure core frequency as 1800MHz.

SYS_PLL_RAT=7
CGA_PLL1_RAT=18
CGA_PLL2_RAT=16

Hello salmon tian,

In LSDK 1906, only rcw_1600_sdboot.rcw(core frequency of 1600MHz) is provided.

Thanks,

Yiping
