MESA_PKTGYRO_TEST(9)

loadrt mesa_pktgyro_test [count=N|names=name1[,name2…]]

This component is written in order to test the PktUART driver for Mesa. It resembles partly Andy Pugh’s mesa_uart.comp .

This module uses the names= mode of loadrt declaration to specify which PktUART instances to enable. A check is included to ensure that the count= option is not used instead. For simplicity we test only one PktUART instance, therefore load the component like this:

The PktUART instance names are printed to the dmesg buffer during the Hostmot2 setup sequence, one for each PktUART instance included in the bitfile loaded to each installed card during the Hostmot2 setup sequence. Type "dmesg" at the terminal prompt to view the output. If you want to work with more than one PktUART instance, consult Andy Pugh’s mesa_uart.comp

In order to compile and install do:

The component exports only one function, namely receive, which needs to be added to a realtime thread. To test this component set DEBUG=5 before and execute this HAL script:

Check linuxcnc.log for debug output.
