| 35 | <h4>DESCRIPTION</h4> | |
| 36 | <ul> | |
| 37 | Set physical memory at location <i>address</i> to <i>value</i>. | |
| 38 | The size option determines how many bytes are written. | |
| 39 | Valid size options are 1, 2, 4, or 8. | |
| 40 | The default size is 4 bytes. | |
| 41 | The -count option lets <i>value</i> to be written to consecutive | |
| 42 | locations of size <i>size</i>, starting at <i>address</i>. | |
| 43 | The default count is 1. | |
| 44 | If specified, the arguments <i>size</i> and <i>count</i> determine the | |
| 45 | width of each write and how many writes occur. | |
| 46 | Each write advances through memory by <i>size</i> bytes. | |
| 47 | <p> | |
| 48 | In the deprecated form, the default size argument is 4 bytes, but can be 1, | |
| 49 | 2, 4, and 8*N (N > 0) bytes. | |
| 50 | <p> | |
| 51 | The behaviour of set is undefined if <i>value</i> does not fit in the | |
| 52 | specified size in bytes. | |
| 53 | <p> | |
| 54 | By default, <i>address</i> is treated as physical. | |
| 55 | The -pa, -ra, and -va flags override this default. | |
| 56 | More details on these and the -context and -partition flags can | |
| 57 | be found <a href="flag_addressing_options.html">here</a>. | |
| 58 | If -va is given, <i>address</i> is virtual and is translated in the context | |
| 59 | of the current cpu, specified by <a href="cmd_pselect.html">pselect</a>. | |
| 60 | This may be overriden by the <a href="flag_cpu.html">-cpu</a> flag. | |
| 61 | </ul> | |
