16 default ETRAX_KGDB_PORT0
18 Choose a serial port for kernel debugging. NOTE: This port should
19 not be enabled under Drivers for built-in interfaces (as it has its
20 own initialization code) and should not be the same as the debug port.
22 config ETRAX_KGDB_PORT4
24 depends on ETRAX_SERIAL_PORTS = 5
26 Use serial port 4 for kernel debugging.

35 Waitstates for flash. The default value is suitable for the
36 standard flashes used in axis products (120 ns).
38 config ETRAX_MEM_GRP2_CONFIG
40 depends on ETRAX_ARCH_V32
43 Waitstates for SRAM. 0 is a good choice for most Axis products.
45 config ETRAX_MEM_GRP3_CONFIG
47 depends on ETRAX_ARCH_V32
50 Waitstates for CSP0-3. 0 is a good choice for most Axis products.
51 It may need to be changed if external devices such as extra
52 register-mapped LEDs are used.

56 depends on ETRAX_ARCH_V32
59 Waitstates for CSP4-6. 0 is a good choice for most Axis products.

63 depends on ETRAX_ARCH_V32
66 SDRAM configuration for group 0. The value depends on the
67 hardware configuration. The default value is suitable
68 for 32 MB organized as two 16 bits chips (e.g. Axis
69 part number 18550) connected as one 32 bit device (i.e. in

73 hex "SDRAM_GRP1_CONFIG"
74 depends on ETRAX_ARCH_V32
77 SDRAM configuration for group 1. The default value is 0
78 because group 1 is not used in the default configuration,
79 described in the help for SDRAM_GRP0_CONFIG.
81 config ETRAX_SDRAM_TIMING
83 depends on ETRAX_ARCH_V32
86 SDRAM timing parameters. The default value is ok for
87 most hardwares but large SDRAMs may require a faster
88 refresh (a.k.a 8K refresh). The default value implies
89 100MHz clock and SDR mode.
91 config ETRAX_SDRAM_COMMAND
93 depends on ETRAX_ARCH_V32
96 SDRAM command. Should be 0 unless you really know what

98 mappings such as in a MCM)..

102 depends on ETRAX_ARCH_V32
105 Configures the direction of general port A bits. 1 is out, 0 is in.
106 This is often totally different depending on the product used.
107 There are some guidelines though - if you know that only LED's are
108 connected to port PA, then they are usually connected to bits 2-4
109 and you can therefore use 1c. On other boards which don't have the
110 LED's at the general ports, these bits are used for all kinds of
111 stuff. If you don't know what to use, it is always safe to put all
112 as inputs, although floating inputs isn't good.
