Hi, unfortunately i have some two problems with my new STM32F4 core module. I uploaded the actual bootloader 1.015 and Midibox NG 1.029 version. This ports are wired J16, J8/9, J19, J15A and J15_S. Problem 1: The event Event Pool Allocation is 24480 of 24576 bytes (99%) exactly like using the LPC1769 core. Shouldn't be there more bytes available :question: Problem 2: The LCD does not work (backlight and contrast are ok). It is a 2x16 HD44780 display. I have triple checked the wiring and soldering. TK, your help is needed :) Best regards Marxon

Im planning a prototype of the stm32f4-core using the stm32f4discovery. unfortunately i cant find any notes on J28. nothing in the diagram and nothing in the mios32-include-files either.... basically i want to connect two ks0108 lcd-displays, which will need 4 cs-signals. on the lpc17-core they are provided via J28, but theres nothing like that on the stm32f4-core. am i missing something or is this just not implemented (yet) ?? mOnO
