What is the maximum SPI clock speed in SAM E70? yep,
its pretty clear,
E70tryhard seems like a good title.
Thanks a lot.
Again, if you have any experience in USB or external flash, then you can help me.
I got stuck on...
What is the maximum SPI clock speed in SAM E70? in page 931, section 40.7.3.3 Clock Generation
It says that the SPI clock is generated by dividing peripheral clock between value 1 and 255.
If that is so, then if my peripheral...

SAM E70 External Flash interface Also in datasheet, im section 10.1.5 Flash Memories, the datasheet says that the QSPI interface mapped at address 0x80000000 extends the flash size by adding an external SPI or...

SAM E70 External Flash interface In SAM E70 Datasheet, page 41, section 9. Product mapping, I could see QSPI MEM defined from 0x80000000 to 0xA0000000.
Does it mean that the flash chip interface via QSPI can be...

Now am feeling pretty confused.
My bad. So, yes, with 300MHz core clock, the peripheral clock can have a max of 150MHz. You are right.

Try giving 1111 instead of freq in tc_find_mck_divisor() and tc_write_rc() let me know what happens.
Has anybody interfaced an external flash using Atmel SAM controllers
Any updates on this USB host operation in sam e70?
Exactly & am supplying it externally.
