CONFIG_SYS_INIT_RAM_SIZE may be used out of the board header file. Some boards use CONFIG_SYS_INIT_RAM_END for the same purpose. To unify the macros, use CONFIG_SYS_INIT_RAM_SIZE for all. Signed-off-by: York Sun <york.sun@nxp.com> CC: Mario Six <mario.six@gdsys.cc> Acked-by...

Noinit RAM,故名思意就是未被初始化的变量,我们编程的时候也知道,如果定义了一个常规的变量,一般编译器都会将其初始化成固定数值(一般是0xFF),系统每次复位的时候都赋值为一个固定的初始值。 但是有些场景下我们需要一些特定变量,这些变量在系统复位后也能保持复位前的值,不发生改变,Noinit RAM有用的地方就在...
①系统上电后,首先将PROG_B置为高电平(通过外接上拉电阻),之后FPGA将PROG_B置为低电平,此时配置存储、BRAM、FF等复位为初始状态,INIT_B被拉低电平,IO倍配置为高阻态,如果PUDC_B为低电平,IO配置内部上拉电阻使能,PROG_B延时100 μs充分复位内部逻辑后,将PROG_B置为高电平。 ②INIT_B保持低电平直到PROG_B...
(* ram_init_file = "my_init_file.mif" *) reg [7:0] mem[0:255]; Note: You can also specify the synthesis attribute of an inferred RAM, whose implementation you want to control, in a comment following the Variable Declaration. In the comment, the synthesis keyword must precede the sy...
Note: Analysis & Synthesis also recognizes the synonymous synthesis attribute syn_ram_init_file, which behaves identically to the ram_init_file synthesis attribute. To use the ram_init_file synthesis attribute in a VHDL Design File (.vhd), first declare the synthesis attribute with a string type...
