targets.py : add IAR for NUCLEO_F746ZG and DISCO_F746NG
iar.py: in case of Cortex-M7F, change it into Cortex-M7 and add --fpu
VFPv5_sp
I have been confirmed that for Cortex-M4F we don't need to add the --fpu
VFPv4_sp
UART_IT_TC was enabled instead of UART_IT_TXE
This was causing an issue because UART_IT_TXE (and not UART_IT_TC) was disabled by same function.
Consequently if a transfer was ongoing when serial_irq_set() was called to disable IRQ, UART_IT_TC would still trigger (once).
Side effect is maybe speed: I guess using UART_IT_TC prevented implementation of continuous transfer.
This commit is focused on solving an issue observed with TARGET_STM32F4. It doesn't presume it should or shouldn't be done for other targets.
My previous commit, c6d2c81, broke Keil builds and maybe even IAR.
I need to learn how to read C code :) I thought I was masking off the
O_BINARY bit only for GCC builds but it turns out that my update was
in the fall-through case for all toolchains. This commit now places
the O_BINARY masking operation into a GCC specific #ifdef clause.
Testing:
I tested the same fopen("/local/out.txt","rb") code as before but this
time I built it with the online compiler and GCC_ARM. I tested the
resulting binaries on mbed-LPC11U24 and mbed-LPC1768 boards.
Thanks to @neilt6 for catching & reporting this!
Adding additional 'defined' statements to line 62 of parse_pins.cpp should in theory enable the rpc libraries for all other Nucleo boards, since all stm32 parts use the same pin labeling scheme i.e. P(port)_pinNumber e.g. PA_3,
PC_15 e.t.c.
Fixes issue #1562 reported by @justbuchanan.
When building code with GCC-ARM / newlib, attempting to use the
b (binary) mode in a fopen() call would fail. newlib would parse
this option and pass it down to the LocalFileSystem open call which
didn't like the unexpected O_BINARY flag in openmode.
The openmode_to_posix() function in retarget.cpp would never set the
O_BINARY flag for the other toolchains but for GCC it would just pass
down whatever newlib placed there. This commit masks out the O_BINARY
bit so that it never gets passed down to the file system drivers, just
as occurs for the other supported toolchains.
Test case:
FILE *fp = fopen("/local/out.txt", "rb");
I tested that code on mbed LPC1768 and LPC11U24 boards while using
GCC_ARM as the toolchain. It failed on both platforms previous to
this change and succeeded there after.
UDP based protocols such as DTLS may fragment large packets, resulting
in many packets being sent at once. This can lead to significant/irrecoverable
packet loss on systems that respond to packets slower than network transfers.
Increasing MEMP_NUM_NETBUF to 8 allows lwip to handle a DTLS handshake
successfully and should be more robust for similar protocols.
