AXM0F343-64 latest schematic and J-Link

hello

we are doing the pcb to the AXM0F343 64

  1. please provide us the latest schematic for the AXM0F343 64. We found this AXM0F343-256-868-1-GEVB (onsemi.com)
  2. do you have Hardware / RF technical note for the pcb , the impendence out put to check the pcb , and more …
  3. is segger is the only option to " program " the chip ? what is the exact pins for the programmer
    • programmer : for programming and not debug just programming
    • base on your’s schematic the AXM0F343 has PB6 :SWDIO , PB7 : SWCLK …GND RESET AND VCC , do we have to use the segger programmer or OEM "simple " J-LINK can do the job, since it is ARM BASE CORTEX M0? Like (that we can provide for our customers’ )

Hi Yaniv,

  • please provide us the latest schematic for the AXM0F343 64
  • is segger is the only option to " program " the chip ?
    • our GEVB boards come with an OnBoard J-Link probe (running on the ATMEL chip on the backside) that we licensed to be used as programmer/debugger for the AXM0F343 specifically mounted on that GEVB. One could re-route the SWD connections to another IC but this is not covered by our license.
    • to program/debug our parts we recommend to use one of the official J-Link Debug Probes by SEGGER – the Embedded Experts together with the adaptor 9-Pin Cortex-M Adapter (segger.com).
  • Since it is ARM BASE CORTEX M0 is simple programmer can do the job ?
    • yes, any J-Link probe can be used. The clone you linked should work (I did not test it). The ST one will not work.
  • what are the exact pins for the programmer
    • as you correctly write the AXM0F343 has PB6 :SWDIO, PB7 : SWCLK, GND, RESET, VCC, and DBG_EN (needs to be pulled up in order to enter debug mode).
