Instead of user defined symbols in assembly files or C files,
use linker scripts to add heap and stack - this is inconsistent
with ARM std linker scripts
When activating an endpoint assign new data rather than ORing
data to it. This ensures that values set from the previous use
do not effect the current configuration.
Update the patch "Create HAL_PCD_EP_Abort" to fix bugs.
This patch adds the low level functions USB_EPStopXfer, USB_EPSetNak,
USB_EPClearNak and the high level function HAL_PCD_EP_Abort so that
transfers can be stopped.
The functions USB_EPSetNak and USB_EPClearNak allow nak to be enabled
or disabled for an endpoint, preventing or allowing further transfers.
The function USB_EPStopXfer stops pending reads and writes started by
USB_EPStartXfer along with clearing and masking any interrupts enabled
by USB_EPStartXfer.
The function HAL_PCD_EP_Abort aborts any transfers on the given
endpoint. When this function completes the transfer interrupt
is guarenteed not to fire for this endpoint. Furthermore, the size
of data transferred during an aborted read can be found by calling
the function HAL_PCD_EP_GetRxCount.
Other notes on this Change:
1.
Prior to this patch the interrupt USB_OTG_DOEPINT_EPDISD was not
handled. When an OUT endpoint was disabled this interrupt occurred
causing the CPU to get stuck repeatedly handling this interrupt. This
is because this interrupt was unmasked but nothing cleared this
interrupt. This patch also adds code to handle and clear this
interrupt to prevent a lockup.
2.
Stopping a transfer on an OUT endpoint requires global nak OUT to
be in effect. Even with this being done, having entries in the rx fifo
prevented an OUT endpoint from being disabled. This behavior is not
mentioned in the Reference Manual.
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.
