SerialWireOutput was outputting 1 character per 32-bit write to the ITM stimulus port. This is inefficient, and causes processing problems with some viewers due to them receiving 3 NUL bytes between each desired character. Rework to allow us to be more efficient, and eliminate those NUL bytes: * Retain existing mbed_itm_send() and clarify it's a single 32-bit write. * Add new mbed_itm_send_block() that is appropriate for sending character data, and modify SerialWireOutput to use it. * Move "wait for FIFO ready" check to before the write, rather than after. One minor correction - FIFOREADY is a single bit of the register read. Don't interpret reserved bits. |
