| 75 | Implementation Notes: |
| 76 | --------------------- |
| 77 | |
| 78 | Due to the RAM/flash bus arbitration problem the suggested workaround |
| 79 | had to be implemented. It works okay. On the downside is that you |
| 80 | can't really check whether 'erase' is complete by polling flash as it |
| 81 | is usually done. Instead, the flash driver simply waits for a given |
| 82 | time and assumes that erase then has passed. This behaviour is |
| 83 | identical to what the VxWorks driver does; also, the same timeout (6 |
| wdenk | d681543 | 2003-05-12 09:51:00 +0000 | [diff] [blame] | 84 | seconds) was chosen. Note that this timeout applies for each erase |
| wdenk | 60fbe25 | 2003-04-08 23:25:21 +0000 | [diff] [blame] | 85 | operation, i. e. per erased sector. |
