Hi I add small spi lcd on RT3050. This lcd controller is S6D0151. S6D0151 transfer is tree byte command then tree byte data. I use spigen mruby rapper. This rapper use SPIGENIOC_TRANSFER. I try to send tree byte command. But spi transfer is six byte. This is reason. sys/dev/spibus/spigen.c error = copyin(st->st_command.iov_base, transfer.tx_cmd, transfer.tx_cmd_sz = transfer.rx_cmd_sz = st->st_command.iov_len); This lcd not work six byte transfer. How do I fix this ? Regards Hiroki Morihelp
