BTaddon - Uart errors in latest build

[quentynt]

in recent build ( as of todays date) i now get constant UART errors in any action - build was with out error, flash was without error. Re cloning and rebuilding / flashing results in the same error on Linux mint ( ubuntu). This is the same laptop / lunux build i have used for a whie without errors

Did you flash the device? Since your output states you don't have a fpga image loaded...

[edit] yeah you did, I see the four images. still the hw status doesn't show a loaded image, which would indicate a error. and if no fpag image loaded, you will get errors since the device will fail to operate properly.

make clean
make -j
 ./pm3-flash-all

what is the output of those steps?

@quentynt remove PLATFORM_EXTRAS=BTADDON try again?

[quentynt]

@quentynt remove PLATFORM_EXTRAS=BTADDON try again?

that seems to have resolved the issue... there must be an error somewhere when you have the blueshark module connected but not in use ?

[iceman1001]

the fpga_ring buffer seem to be the problem, I let me adapt it.
