imx6dl spi transmit more than 32bit data

[dingfeng]

I try to test the spi of imx6dl with spidev_test.c(https://github.com/torvalds/linux/blob/master/tools/spi/spidev_test.c), it will report error  when I set the "-b" parameter to more than 32 , does the imxdl has a limit of 32bit?

Hello,

   SPI of i.MX6DL can transfer more than 32bit data; at least 2^7 words (ECSPIx_CONREG[BURST_LENGTH]).

Yuri.
