Hi All,
I have problems doing that and want to discuss with you to get best decision.
The problems are:
* flash command set different from one currently supported (current
command set is defined through macro-definitions)
* all pages need to be unlocked one by one with CLB command prior to
erasing even if EA (erase all) command is used.
I think, good way to do this support is to have some structure, which
describes flash interface (command set, capabilities, etc)
For example:
enum {
CMD_WP,
CMD_WPL,
CMD_EA,
................
CMD_LAST,
CMD_UNSUPPORTED = 0x100
};
const uint16_t cmd_set_default[CMD_LAST] = { <default cmd set> };
const uint16_t cmd_set_L[CMD_LAST] = { [CMD_WP] = 0x01, [CMD_WPL] =
0x02 , <etc.> };
struct flash_descriptor {
uint16_t num_pages,
uint8_t num_nvmbits,
uint16 ** cmd_set,
}
Something like that. Any other ideas?
Best regards, Denis Kuzmenko.
