I'm looking to start a new design based on the ARM Cortex-M7 and have been reading thousands of pages of documentation ( not done yet of course ). I am able to design my own schematics and PCBs so I'm trying to first determine the very bare minimum to start.
1. power circuits to accommodate a ATSAMV71Q21
2. the ATSAMV71Q21 itself
3 USB circuits to attach the board to a PC
I may be wrong, but my understanding thus far is that the SAM V71 embeds an Internal ROM for the SAM Boot Assistant (SAM-BA), In Application Programming functions (IAP) and Fast Flash Programming Interface (FFPI), ( <- right from the doc ) and that this sets up serial communication via the UART0 and USB.
Initially I would simply be using the internal ROM, embedded FLASH and SRAM ( although I might add in an external 16Mb SRAM chip ).
Granted, this minimum configuration wouldn't be able to do much as there would be no external peripherals just yet, but my plan would be to connect a series of header pins for testing purposes.
Any feedback would be greatly appreciated.
Thanks in Advance.
Usually for MCU vendor specific questions, it is easier for MCU vendors to have someone to monitor and reply as ARM staffs might not be familar with their products. Regarding upload new code into the embedded flash, normally you can just use JTAG/Serial Wire debug connection to do that inside software development suites like Keil MDK or IAR EWARM. The tool will be able to load some flash programming code into SRAM, and execute that to program the flash. So you don't need any extra connection for flash programming. If you need additional information on this, you can also ask your question on Atmel website: www.atmel.com/.../community.aspx Regarding designing your own PCB, have you look at SAMv71 Xplained Ultra? www.atmel.com/.../atsamv71-xult.aspx www.atmel.com/.../Atmel-42408-SAMV71-Xplained-Ultra_User-Guide.pdf It seems to be almost a bare minimal system (but it also included a second MCU that do debug connection based on CMSIS-DAP). The CAD files are included in the zip file www.atmel.com/.../Atmel-42408-SAMV71-Xplained-Ultra_User-Guide.zip
Hi
Im trying to do the same (ie. minimal circuit board).. did you reach any information or design? thank you..
