Summary | 0002090: armStoneA9: When using ttymxc2 as serial console, ttymxc1 soes not work anymore | ||||
Description | Customer wants to use ttymxc1 in Linux. So he changes serial console from ttymxc1 to ttymxc2 in the bootargs in U-Boot. But when he tries to access ttymxc1, the system hangs. If he completely removes console support from the kernel, ttymxc1 does work correctly. | ||||
Steps To Reproduce | Steps as given from the customer: - Switch console from ttymxc1 to ttymxc2 in U-Boot bootargs - Boot to Linux, console will show output on ttymxc2 now - Type "echo hello >/dev/ttymxc1". The system will hang. | ||||
Additional Information | Maybe some initialization is missing as it is assumed to have been done in U-Boot already. Judging from the Vybrid implementation that was based on i.MX6 code, maybe the FIFO is not enabled correctly. So we could probably cross-check with what we changed in the Vybrid code to make it work. | ||||
