SAM E70 using TC0 to trigger SPI DMA transfer
it might be better to make the ADC free running at the target frequency (adjusting a clock source as needed) and have data ready event trigger the DMA. We are using external ADCs...

SAM E70 using TC0 to trigger SPI DMA transfer
I´m also very interested in this problem. I also interface with an external ADC and want to have a fixed intervall SPI Transfer.   As some already have failed with TC0, I...

SAME54 Xplained Pro - DPLL with XOSC1 and Atmel Start
jcandle wrote: I used 32KHz, but you could run 12MHz through a GCLK /12 to get 1MHz and then feed that to DPLL.  I think you need to use GCLK3 to feed back to sources......

AS7 High CPU Usage When Opening a Large SAM4E Project
I experience the same behaviour. Larger C++ Project for SAME70, takes quite a while for the IDE to become responsive after loading. Do you use a C or C++ Project? My wild guess...

ATPROGRAM utility is taking some secodns to flash 128KB Bytes in flash.
try to increase the clock of your debugger. I used a swd interface and added "-cl 2mhz" to atprogram call which made it much faster. Maybe this is your problem as well...

Set GPNVM bit (BOOT_MODE) with atprogram.exe for SAME70
you should not set to 0, because then bit 6 is 0 and this is not recommended.   --values 0x40 (=bit6 + boot from rom) --values 0x42 (=bit6 + boot from flash)

SAME70 and SAMV70 dont have I2s (inter sound) ports?
Good to know... I used SSC for Left justified Audio and had no problem (Grab a mono stream with dma (16 of 32 bit) out of a stereo PCM stream). Glad we did not choose a chip...

Atmel Studio 7 - ASF and C++
Hi,   I think your C++ complier is missing some Defines from the commandline. Go to the project properties and check "ARM/GNU C Compiler" and look at the sub entry Symbols....

SAME70 and SAMV70 dont have I2s (inter sound) ports?
I quote the errata section of the datasheet:   61.7 Inter-IC Sound Controller (I2SC) Issue: I2SC not available The I2SC is not available. Workaround: None. BOOM   BTW...

Set GPNVM bit (BOOT_MODE) with atprogram.exe for SAME70
I opened a support ticket and got help from atmel support team.   For those who are interested: Setting GPNVM bits is done with the commands for setting "Fuse bytes". Here is...

Hi,   I was using MCI both with DVK and also with a custom design. No problem without Caches. I can also not see why the caches would be necessary, they are bascically just a...

I am not expert regarding DCache. But I think using DMA and DCache togehter is probably quite tricky and needs well written drivers. I made the same observation, that ASF USB MSC...
