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.
