Previously, we weren't filling in RX1 frequecny in rx_window1_config
structure. However, everything worked as in LoRaPHY::rx_config() API
there was a check which filled in correct RX1 frequency.
Now we are filling in RX1 freq. properly while we are computing
parameters for RX1 window.
The idea behind the method post_process_no_reception() is to post
process any outgoing TX but we shouldn't do that if a CONFIRMED message
is outgoing and there are still some retries left.
After transmission we should change the state before invoking opening of
slots as we may start receiving in the rx slots and the state would
suddenly change from SENDING to RECEIVING without going through the
ACK_WAIT state (in case of CONFIRMED messages). Tests show that after
this slight adjustment, our number of ack retries have significantly
reduced.
LinkADRReq mac command can be used by the network server to set a
certain level of QOS using NbTrans field which is applicable to
Unconfirmed traffic only for 1.0.2 spec.
This commit introduces mechanisms to facilitate this QOS. It means to
repeat an outgoing unconfirmed message NbTrans times without changing
its frame counter.
For class C, we have retired the ack_expiry_timer_for_class_c and have
replaced it with another timer which mimics the RX2 closure as in Class
A but doesn't actually close RX2 window. It's just a mechanism by which
the state machine is informed that the you can proceed forward, we have
not received anything in RX2 window either. This is needed as RX2
doesn't timeout in class C (i.e., the radio remains in continuous mode).
In addition to that we need to close any pending timers for Receive
windows after the MIC has passed and the Duplicate counter check has
also been passed.
Before going after an automatic uplink, we should check if there was an
automatic uplink already ongoing, i.e., the ack for the previous
automatic uplink cycle has not been received.
If there is we shouldn't queue the new automatic uplink and wait for
the previous Ack cycle to complete.
For Arm toolchain build, Mbed 2(classic) programs occur an unexpected error if there is "#include "mem_XXXX.h"" in the script file.
It seems that the linker script can't find the include file because "mem_XXXX.h" file is not in the same path with the linker script.
(Refer to Issue #6975.)
To address this issue, I remove inclusion processing and define the related macros at ARMCC linker script file.
Change error from `MBEDTLS_PLATFORM_HW_FAILED` to
`MBEDTLS_PLATFORM_HW_ACCEL_FAILED` and the value to 0x70,
as the previous value cannot be used as a low level error code.
When socket created using accept() is closed by calling the close()
method, "delete this" is executed which triggers the destructor call
on TCPSocket which in turn calls close() once again. Because _stack
is already 0 this results in a hard-fault.
Add a check that skips the rest of the close() method is the _stack
is already 0.
If the packet is already handed over to the PHY layer, we shouldn't be
able to cancel that particular transmission. In addition to that if the
backoff timer is either not applied or has been deactivated, should end
up in no-op rather than having normal termination. A new error code has
been introduced to cover no-op cases. This error code replaces the
compliance test related error code which is no longer relevant.
clear_tx_pipe() does nothing if:
- The stack cannot cancel TX (already handed over to PHY)
- The backoff timer is not active at all
- The event is disaptched to schedule
stop_sending() will only post process ongoin TX if the pipe was
definitely cleared.
If the specified frequency exceeds the upper limit and lower limit at SPI driver, an error is output, but this does not match policy with other renesas drivers. Thus I revises the processing as follows.
- If "hz" is maximum over, it is rounded by the maximum value.
- If "hz" is minimum under, it is rounded by the minimum value.
### Description
Memap will create a bunch of warnings about "Unknown object name" when
parsing a map file created for the RZ_A1H and the GR_Peach. Theses
warnings are sperious; the information in these sections does not belong
to an object file. This PR silences these warnings.
Fixes#6258

Compilers allocate some section of memory without using wrapper function,
which is later freed when wrappers were initialized. Since the allocated
memory didn;t contain wrapper header the pointer got corrupt when calling to free.
This implementation of signature addition during malloc and signature check during
free helps in freeing the memory allocated by wrapper functions properly and
also the internal memory allocated by compilers (without malloc wrappers).
malloc guarantees aligned memory. If we add an alignment here, we are adding
additonal unused 4 bytes. Each allocator has its own 4/8 byte header
(GGC / ARM have 4 bytes).
So if user request for 8 bytes of memory stats will add 8 + allocator 8.
However if we remove the alignment in stats header, allocator will consider
add 4 bytes to 12 byte request and zero padding.
It will be beneficial to leave the padding to allocator.
Change the base time value to more realistic:
START_TIME = 1537789823 # GMT: Monday, 24 September 2018 11:50:23
This fix has been proposed by STM in order to enhance test efficiency.
Current test version did not detect problem with RTC reset on F1 family boards since the base time was too small.
