This fixes bug #1042, which occured when an RX->OFF->RX sequence
happened quickly enough that the loop in rx_mode() did not see the
change. As a result, the enable_baseband_streaming() call at the start
of that function was not repeated for the new RX operation, so RX
progress stalled.
To solve this, the vendor request handler now increments a sequence
number when it changes the transceiver mode. Instead of the RX loop
checking whether the transceiver mode is still RX, it now checks whether
the current sequence number is the same as when it was started. If not,
there must have been at least one mode change, so the loop exits, and
the main loop starts the necessary loop for the new mode. The same
behaviour is implemented for the TX and sweep loops.
For this approach to be reliable, we must ensure that when deciding
which mode and sequence number to use, we take both values from the same
set_transceiver_mode request.
To achieve this, we briefly disable the USB0 interrupt to stop the
vendor request handler from running whilst reading the mode and sequence
number together. Then the loop dispatch proceeds using those pre-read
values.
This changes m0_rom_to_ram to read directly from the ROM region, rather
than copying from where .text has been copied to RAM.
Previously the second .text section would be merged with the first one,
so the M0 image would be copied to RAM during `pre_main`. However, on
newer linkers the sections are not merged together so the second .text
section did not get copied to RAM.
fixes#936
Previously the firmware would re-initialise the bulk endpoints on
every transceiver mode change including a USB data toggle reset,
which could cause the first bulk packet (512-bytes) to be dropped
by the host if the PID no longer matched.
Perform PortaPack initialization separately from and earlier than UI initialization. Track if PortaPack was detected, provide (mostly useless) pointer if so. Put "weak" declarations into respective headers. Moving #includes around.
Just a very rough merge to get off the ground. Major parts are not yet
implemented. The mixer intergration is in a messed up state. Part which
need work have been marked with XXX
