The K64F Ethernet driver installs an interrupt handler that sets thread
flags, and this could be called before the thread was initialised, so it
would use a NULL thread ID.
This triggers an RTX error-checking trap in debug builds, and could also
lead to other problems with received packets not being processed.
Adjusted so the RX interrupt handler does nothing if the thread isn't
initialised yet, and manually trigger a RX event flag after initialising
the thread in case any interrupts were ignored.
An alternative would have been to implement eth_arch_enable_interrupts,
but this mechanism is not present in the EMAC world - drivers will have
to start returning interrupts in their power up.
Fixes#5680
We currently set the lwIP pbuf pool size small - to 5 x 576-byte
buffers.
This is insufficient to hold a single DTLS handshake flight, so can
cause cloud client connections to fail. STM-based platforms are failing
handshake because of this. (K64F works because it doesn't use the pbuf
pool for reception, but lwIP does recommend drivers use the pbuf pool).
Not changing the default memory sizes here, as intended for a patch
release, but adding mbed configuration options to allow the numbers to
be adjusted for memory tuning in an application.
In a future minor revision, I would recommend increasing the default
PBUF_POOL_SIZE - we are well below lwIP's out-of-the-box default - and
offsetting by a reduction in MEM_SIZE for the drivers that don't use
PBUF_RAM.
Target of LPC1769 links to mbed LPC1768.
The PinNames.h has conditional compile for the pin names.
LWIP lpc17xx emac driver modified to allow LPC1769 target
Commit f602c936 incorrectly started defining LWIP_DEBUG as either 0 or
1.
lwipopts.h locally was changed to use #if, but all existing users
continued to use #ifdef. Therefore defining it to 0 was accidentally
enabling it for quite a few users.
This would have pulled in some unwanted lwIP code, and affected some
drivers, eg k64f_emac.c allocating an extra 2K of stack.
Correct lwipopts.h to either define it as 1 or leave it undefined, and
change the #if tests back to #ifdef, so all are consistent.
Merged lwip 2.0.2 stable path 1 from https://github.com/ARMmbed/lwip
Patch allows lwip to do autonomous address configuration for prefixes
that are not on-link.
