I hope to use the on-board LEDs to work around the debug problems with the PCL Logic board (see above).

* arch/arm/stm32/Make.defs: Don't build stm32_rtc.c if CONFIG_RTC is not

selected. Doing so will cause errors if other configuration dependencies
|
|
||||||
are not met.
|
|
||||||
* configs/stm3210e-eval/src/up_lcd.c: Color corrections for SPFD5408B LCD
|
|
||||||
do not work with R61580 LCD.
|
|
||||||
* configs/pic32-starterkit: Beginning of a configuration for the Microchip
|
|
||||||
PIC32 Ethernet Starter Kit. Hmmm.. I don't have a clue how to test this
|
|
||||||
with no serial port?!
|
|
||||||
* lib/stdio/lib_fclose.c: fclose() always returns an error (EOF) when it
|
|
||||||
closes a read-only file. This is because it calls flush() which will
|
|
||||||
fail on read-only files. No harm is done other that a bad value is
|
|
||||||
returned.
|
|
||||||
* arch/sim/src/Makefile: Correct build issue for sim/nsh2 target. Old
|
|
||||||
libboard.a was not being cleaned.
