Dear all,

I use a spidev device to write 200 bytes to spi.

Why are there gaps between every 25 bytes?

How to remove this gaps?

Hi Renat

one can try to adjust BURST_LENGTH value of register ECSPIx_CONREG. If

this will not help, seems delays are caused by processor internal bus latencies

and unfortunately there is no way to change this.

Best regards
igor
