Cannot use AT45DB161 dataflash with AT91SAM7S256....
VERSION: Nut/OS Veta 4.9.9
FILE: nut/dev/at45db.c
LINE: 373
This line:
#if defined(MCU_AT91SAM7X) || defined(MCU_AT91SAM7SE) ||
defined(MCU_AT91SAM9260) || defined(MCU_AT91SAM9XE)
Must be replaced by this:
#if defined(MCU_AT91SAM7S) || defined(MCU_AT91SAM7X) ||
defined(MCU_AT91SAM7SE) || defined(MCU_AT91SAM9260) ||
defined(MCU_AT91SAM9XE)
Cannot use AT45 flash with a AT91SAM7S256 without this modification.
Here my test code:
/* INITIALIZE DATAFLASH */
if ((at45db = At45dbInit(SPI0_BASE, 0)) == -1) {
puts("Dataflash init FAIL.");
} else {
printf("Dataflash init OK.\n");
printf("Page size is %u bytes\n",At45dbPageSize(at45db));
printf("Page number: %u\n",At45dbPages(at45db));
}
while(1) {
if(At45dbPageRead(at45db, 0, Buf, At45dbPageSize(at45db))) printf("Error
reading page 0\n"); else printf("Succesfully read page 0.\n");
NutSleep(125);
};
Please add this mod to next release (or beta)
Thank!
