in a previous post I ask why in the following startup code
/* SRAM initialization code*/
/* Loops to cover L2SRAM, stmw allows 128 bytes (32 GPRS x 4 bytes) writes */
stmw r0, 0(r11) /* Write 32 GPRs to SRAM*/
addi r11,r11,128 /* Inc the ram ptr; 32 GPRs * 4 bytes = 128B */
bdnz init_l2sram_loop /* Loop for 48k of SRAM */
SRAM data is not initialized to value 0x00 in all bytes and you answer me that
" There in no need to have ram initialized with 0x0000 0000 patern.
And it is also not recommended to have all 0 in SRAM.
Your RAM will be initialed with R0 to R31 GPRs in 128bytes loops. And the address on R11 will be incremented by 128B. "
What is the reason to avoid SRAM initialization to pattern 0x0000 0000 ?
