How to write pointer array in stm32 [Copy link]

as follows:

code u8 STB1[][3]={};

code u8 STB2[][3]={};

code u8 code *std[]={STB1,STB2}; This worked in 51 before, but there was a problem when ported to 32 (code has been changed to const). Error message: a value of type "const u8 (*)[3]" cannot be used to initialize an entity of type "const u8 *" . I don't know why? How to change it and why?

const uint8_t STB1[3][3]={{0,0,0}};
const uint8_t STB2[3][3]={{0,0,0}};
const uint8_t * std[]={(uint8_t *)STB1,(uint8_t *)STB2};

Variables defined by const will be compiled into the ROM area, so the array size must be specified [][3] This is not possible.

Yeah, thank you!
