Tool/software:
Hi there!
If I understand correctly, XFR2TR cannot transmit to DDR4. Right?
Since writes from the PRU are posted, my main concern is:
1) Will I get stalls (buffer full) if I write 32 Bytes at a time (8 registers directly to DDR4) every microsecond? How likely?
2) If the addresses are sequential, can this be good for latency? I'm sending data to a ring buffer.
Something like:
LDI32 r0, DDR_RING_BUFF ; aligned
SBBO &r20, r0, 0x4, 4
SBBO &r21, r0, 0x8, 4
SBBO &r22, r0, 0xc, 4
SBBO &r23, r0, 0x10, 4
; .... 32 bytes.
Regards,
Nelson.-
