These fields are all in the board_info These are all set by using the set_board_info procedure. The parameters are the field name, followed by the value to set the field to.
Table 4-1. Common Board Info Fields
| Field | Sample Value | Description |
|---|---|---|
| compiler | "[find_gcc]" | The path to the compiler to use. |
| cflags | "-mca" | Compilation flags for the compiler. |
| ldflags | "[libgloss_link_flags] [newlib_link_flags]" | Linking flags for the compiler. |
| ldscript | "-Wl,-Tidt.ld" | The linker script to use when cross compiling. |
| libs | "-lgcc" | Any additional libraries to link in. |
| shell_prompt | "cygmon>" | The command prompt of the remote shell. |
| hex_startaddr | "0xa0020000" | The Starting address as a string. |
| start_addr | 0xa0008000 | The starting address as a value. |
| startaddr | "a0020000" | |
| exit_statuses_bad | 1 | Whether there is an accurate exit status. |
| reboot_delay | 10 | The delay between power off and power on. |
| unreliable | 1 | Whether communication with the board is unreliable. |
| sim | [find_sim] | The path to the simulator to use. |
| objcopy | $tempfil | The path to the objcopy program. |
| support_libs | "${prefix_dir}/i386-coff/" | Support libraries needed for cross compiling. |
| addl_link_flags | "-N" | Additional link flags, rarely used. |
These fields are used by the GCC and GDB tests, and are mostly only useful to somewhat trying to debug a new board file for one of these tools. Many of these are used only by a few testcases, and their purpose is esoteric. These are listed with sample values as a guide to better guessing if you need to change any of these.
