Philips Semiconductors ISP1362 Linux Stack User’s Guide

5. Configuration

The ISP1362 Linux stack can be configured to work in different ways by using the static compilation time flags. The Rules.Make file in the root directory of the source code selects the global compilation flags. The local compilation flags for the modules are selected in the Makefile of the corresponding module directory.

5.1.Compilation Flags

5.1.1.Global

Table 5-1 shows the compilation flags that are selected in the Rules.Make file and their description:

Table 5-1: Global Compilation Flags

Compilation Flag	Description
DCONFIG_USB_HCDC_OTG	Configures the OTG mode.
	• In the non-OTG mode, only the host stack is enabled without OTG functionality.
	• In the OTG mode, all the modules are enabled.
DCONFIG_1362_PCI	This compilation flag is for the ISP1362 PCI evaluation kit hardware.
DCONFIG_1362_ISA	This compilation flag is for the ISP1362 ISA evaluation kit hardware.
DCONFIG_1362_SA	This compilation flag is for the ISP1362 PXA250 kit hardware.
_16MB_SIZE_	Mass Storage disk size of 16 MB.
DCONFIG_FUNC_DEBUG	Configures function level debugging. When this flag is enabled, the stack prints all
	function entry traces.
DCONFIG_DETAIL_DEBUG	Configures detail level debugging. When this flag is enabled, the stack prints function
	entry traces as well as any important detail level traces.
PHCI_DEBUG	Enables debugging for the Host Controller Driver. The trace level depends on the
	global compilation flags: CONFIG_FUNC_DEBUG and CONFIG_DETAIL_DEBUG.
PDC_DEBUG	Enables debugging for the Device Controller Driver. The trace level depends on the
	global compilation flags: CONFIG_FUNC_DEBUG and CONFIG_DETAIL_DEBUG.
OTG_DEBUG	Enables debugging for the OTG Controller Driver. The trace level depends on the
	global compilation flags: CONFIG_FUNC_DEBUG and CONFIG_DETAIL_DEBUG.
HAL_DEBUG	Enables debugging for the HAL driver. The trace level depends on the global
	compilation flags: CONFIG_FUNC_DEBUG and CONFIG_DETAIL_DEBUG.
MSCD_DEBUG	Enables debugging for the mass storage class driver. The trace level depends on the
	global compilation flags: CONFIG_FUNC_DEBUG and CONFIG_DETAIL_DEBUG.

5.1.2.Host Controller Driver

Table 5-2 shows the Host Controller Driver compilation flags that are selected in Makefile and their description.

Table 5-2: Host Controller Driver Compilation Flags

Compilation Flag	Description
CONFIG_USB_PHCD_EVEN_SCH	Configures the ISP1362 interrupt transfer event scheduling. By enabling this flag,
	the interrupt transfers are evenly scheduled over a period of 32 ms.
CONFIG_USB_PHCD_PING_PONG	Configures the ISP1362 ping pong mechanism. Use the ISP1362 ping pong
	mechanism for the bulk transfers to achieve maximum transfer per millisecond on
	the USB bus.
CONFIG_PHCI_MEM_SLAB	Use memory pool for the HCD endpoint descriptor and Transfer descriptor data
	structures.
