Randomizing backoff by 200ms to 1000ms for Join Requests in a dense
network will add robustness and better chances of reception by the base
station especially in cases of catastrophic network outage and
reconnection.
Frequency setting just after erase operation was causing some data
inconsistencies during write/read operations on some targets (frdm-k82f).
To fix this, frequency setting was moved before flash memory init.
Currently, LwIP segment retransmission time is 12, which is very long
time as each timeout doubles the retransmission timeout.
Make that to 6 as that is same what we use in Nanostack.
Kintis EMAC is consuming 16 rinbuffers for input, and 8 buffers for output.
This is over-use because input packets are immediately allocated from
heap when passed to LwIP. Therefore the number can be creatly reduced.
In case of unusing RTOS, there is no processing against IRQ handler and it causes a linker error.
Therefore, I added this processing with WEAK attribute. Also I added cmain.S file at cmsis/TARGET_CORTEX_A folder.
In case of unusing RTOS, IRQ handler executes "while(1)" and it causes a program freeze.
Therefore, I revised this processing. Also I added the heap setting processing and set the align to 8 byte.
This PR addresses the issue of #8903.
A new boolean variable 'debug' is added to turn off the display of debugging message (by default). It can be turned on when needed.
Description
1. Add new boolean parameter ‘debug’ in function ‘RTWInterface’ in file "RTWInterface.h".
2. Add conditional statement to enable/disable variable ‘GlobalDebugEnable’ in file "RTWInterface.h" to control whether debugging message should be displayed.
For binary compatibility with ARMC5, use the hard ABI variant whenever
we have FP hardware - this is ARMC5's default behaviour, which we do not
override.
Cortex-M4F was already using hard; this brings M7F and M33F into line.
