Hi folks,

  • What does a blinking of the com led mean on stm32f4?
  • When I load lcd interconnection test I get: Hex file contains invalid ranges for MIOS32 STM32!
  • The sequencer app loads fine, I just don't see anything on the display.

I had the frontpanel accidentally connected to J10A, don't know if this makes an issue.

Thanks and regards,

Uli

Hi,

the COM led just shows that no debugger tool is connected.

There is no dedicated LCD interconnection test application for MIOS32, where did you find this .hex file?

Instead, the test is integrated in some applications, such as the MIDIbox SEQ
Just enter "testlcdpin" in the MIOS terminal to get a help page.

Best Regards, Thorsten.

Hi,

the problem was due to a missing solder point.

Me fool, the hex file came from MIOS8 section.

I already have the modified firmware for I²C with 8 MIDI out. Where can I maybe download a compiled version of related Seq application?

Regards & cheers, Uli
