Tool/software:
Hi,
We are trying to Enable UART6 at u-boot using mw.b md.b commands, But Clock is not enabling
below is the Address we used to enable clock
mw.b 0x4A005580 0x2 // writing 0x2 to CM_IPU_UART6_CLKCTRL register
=> md.b 0x4A005580 4 // reading to check weather module is enabled or not
4a005580: 02 00 03 00
We tried to add uart6 node in dts also but didn't help
below is the pinmux we did
{GPMC_A4,(M8 | PIN_INPUT )}, /* uart6_rxd */
{GPMC_A5,(M8 | PIN_OUTPUT )}, /* uart6_txd */
{GPMC_A6,(M8 | PIN_OUTPUT )}, /* uart6_ctsn */
{GPMC_A7,(M8 | PIN_OUTPUT )}, /* uart6_rtsn */
used u-boot version :u-boot-2018.01
If we do clock enable for uart5 that is working, Can you Explain why particularly UART6 Module is not enabling and provide detailed procedure to enable UART at Uboot stage.
Regards
Yashwanth
