I'm looking to deploy an AM3358 into a new application, but one of the issues is the need to handle 9bit serial through the UART, rather than the usual 8bit. On other lower-end devices, eg the TM4C, their supported UART has a special 9bit mode, but it doesn't look like this is available on the Sitara.
Has anyone successfully implemented 9bit serial, or can anyone suggest a suitable way to do it (short of bouncing through a Tiva first)? I'm wondering whether the processor might just be fast enough to accommodate 8bit+1bit transfers, or whether theres something simple which can be done in the PRU?
cheers
