Make the following changes to improve stability:
-When disconnecting set address to disabled to prevent nacks
-Clear EP_SLOW one and only once for every interrupt where it is set_address
-Disable and clear control endpoint interrupts when disconnecting
Even thought the USB phy is disabled during disconnect, endpoints
still nack packets sent. This patch disables all endpoints so after
disconnect no USB traffic will be sent. This allows brief disconnects
of ~200us (or more) to be reliably detected by the host PC.
Update the USBCDC and USBSerial classes to the new API. This patch also
updates the blocking behavior to unblock at the appropriate times and
to let the processor sleep when blocking rather than busy waiting.
Add an allocation free linked list implementation. Additionally add
the class AsyncOp which provides blocking and wakeup funcionality
to simplify making asynchronous operations block.
Stalling endpoint 0 indicates the end of a control transfer.
Return immediately when this occurs rather than continuing processing.
In particular, this patch prevents status from erroneously being
sent when _request_setup returns false inside _complete_request.
Perform processing triggered by user callbacks when USB is being
unlocked rather than synchronously. This prevents recursive callbacks
which reduces stack usage. This also prevents state change inside
the user callback which makes the code easier to reason about.
Initialize the _transfer structure so the behavior is the same
regardless of prior memory contents. This fixes a hang during
USB testing when CI flags are used.
Remove the USBDevice function read_start and automatically start all
reads internally in USBDevice. This patch also renames the function
read_finish to read.
Reverting this feature till IAR 8.x is stable and supported in Mbed OS
for few releases
1. Revert "Add Dynamic heap support to IAR"
This reverts commit 8ee29bbfa2.
2. Revert "Splited RAM section not compatible with dynamic HEAP."
This reverts commit a645bb2a6b.
3. Revert "Add Dynamic heap support to IAR"
This reverts commit 891e1f261b.
Two new block properties available in linker configuration files:
"expanding size" and "minimum size" for IAR 8.11.2 and above
Sample:
define block HEAP with expanding size, minimum size = 16K, alignment = 8 {};
This block will expand to consume all remaining available space in
the range where it is placed. If several such blocks end up in the same
range, they will share the remaining space.
Cannot place a block with expanding size inside another block with
expanding size, inside a block with maximum size, or inside an overlay.
Reference template file is used from IAR8.32 installation available at path
"Embedded Workbench 8.2\arm\config\template\ConvertToIAR\template_project.ewp"
Also added trustzone configs in iar_definitions.json
Few targets have libraries compatible to IAR 7.x, which fail with
IAR 8.x, IAR support for them is removed till updated library is
added.
CI failure seen if IAR is not added as supported target, trying with
release_version as empty string
List of targets affected:
1. UBLOX_EVK_ODIN_W2
2. MTB_UBLOX_ODIN_W2
3. MBED_CONNECT_ODIN
4. MTB_MXCHIP_EMW3166
5. MTB_ADV_WISE_1530
6. MTB_USI_WM_BN_BM_22
7. REALTEK_RTL8195AM
RAM define/section if splited, IAR exanpding size considers just one
section while heap creation which results in smaller chunk for heap.
This commit is to unify the RAM section.
