  1. Thanks a lot for your help.. yes..it's a bummer I think it's not possible to change apb clock from 24Mhz to 48Mhz due to hardware limitations..or maybe I'm wrong. In a common raspberry pi the uart clock is better I think..I was tried to change the speed and it works with no issues at 230400 baud rate. Thanks again
  2. Hi all.. I can't solve one issue with nanopiair h3. I was tried to set the speed of ttyS1 using stty -F /dev/ttyS1 230400 min 0 time 5 -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke -opost -onlcr that works no err messages..but my data at port is like garbage... I see this err under dmesg 21 03:10:02 2017] sw_uart_check_baudset()429 - uart1, select set 1, baud 230400, uartclk 24000000 beyond rance[30000000, 120000000] on the other hand when I check the status of uart root@FriendlyARM:/boot# cat /sys/class/tty/ttyS1/device/status uartclk = 24000000 The Uart controller register[base: 0xf1c28400]: [RTX] 0x00 = 0x00000000, [iER] 0x04 = 0x00000000, [FCR] 0x08 = 0x00000000 [LCR] 0x0c = 0x00000000, [MCR] 0x10 = 0x00000000, [LSR] 0x14 = 0x00000000 [MSR] 0x18 = 0x00000000, [sCH] 0x1c = 0x00000000, [uSR] 0x7c = 0x00000000 [TFL] 0x80 = 0x00000000, [RFL] 0x84 = 0x00000000, [HALT] 0xa4 = 0x00000000 root@FriendlyARM:/boot# So..there's any way to change uarclk from 24000000 to 30000000?
