Release notes for BSP update January 14, 2006
Files updated
bsp20060114.msi
bdWeb.pbxml
Allows registry changes to be saved on an SDCARD
The registry is saved when suspend is executed.
More frequent changes can be saved by including the environment variable
PRJ_ENABLE_REGFLUSH_THREAD in the platform build. If present, this
saves the registry once a second if any changes are made.
This is part of common.reg and the registry keys controlling this are
as follows:
[HKEY_LOCAL_MACHINE\System\ObjectStore\RegFlush]
; To monitor the flushing from an external process add "ActivityName" registry value.
; The activity name is a global named event that filesystem will signal on Registry Activity.
; "ActivityName"=""
; Create an thread in filesys to perform flushing
"SpawnThread"=dword:1
; Make the thread IDLE priority
"FlushPriority256"=dword:FF
; ActivityThreshold specifies the # of reg activity before we force a flush
"ActivityThreshold"=dword:100
; Timeout period for a flush (flush occurs if there have been some changes during this period)
"FlushPeriod"=dword:3E8
So, add the appropriate keys to project.reg if you'd like to change the default behavior.
Auto-detect four or five-wire touch
The touch screen driver will now determine whether the touch screen is a 4-wire type or
5-wire type at boot time.
The touchscreen must be connected before booting to ensure the correct type is determined.
If no touch screen is connected at boot time, it will set it to a 4-wire type.
A new environment variable BSP_TOUCH_TO_SDCARD is used: if set to 1, the touch screen
calibration data is saved to the sdcard. If not defined or set to 0, the calibration
data is saved to flash.
The latest platform builder file bdWeb.pbxml selects storing settings to flash.
ROMSIZE has been lowered to 28mb (01c00000)
This avoids conflict with the default memory map in the U-Boot boot loader.
