Re: SAM-E70 progmem - in system programming and RAMFUNCS

Hi Petro, Thank you for your email (the silence was deafening) :) The SAME70-XPlained board in master would be very similar and a good test case. In doing some archaeology on master, I found that the XULT board has RAMFUNCS enabled! I'm using SAME70N21B, configuration parameters as below: # # AR

Re: NuttX PTP Support

2022-12-06 Thread James Dougherty
Great project! I've done a few commercial implementation of PHY timestamping protocols - IEEE1588 for Ethernet 802.3 and the WLAN version (802.11v2012) for 802.11n. Products with that technology are still shipping today (but that was 10 years ago now). Both are key foundations and building blocks f

Hello James, I've been working with SAMe70 based device and can try to take a look at a case that you are talking about. Do you have any specific config that I can start from? In general I expect that if you fully relocate your program to SRAM you should be capable of reprogramming a full flash,

Hi Markus, I don't know if there is someone already using PTP with NuttX (probably since NuttX is used by many industrial automation companies). I think the first step should be add a PTP daemon for NuttX. The ptpd could be a good candidate: https://github.com/ptpd/ptpd BR, Alan On 12/5/22, M

NuttX PTP Support

2022-12-06 Thread Markus Noll
Dear all, I'm just investigating NuttX a bit as there is definitely more and more momentum coming about it. I was just wondering if PTP (IEEE1588) is supported or if this is planned for the future? Currently, it doesn't look like this, however some Eth-MAC drivers have at least some register-defin

SAM-E70 progmem - in system programming and RAMFUNCS

2022-12-06 Thread James Dougherty
Hi Folks, I've finished a major milestone on some of the firmware I developed for this processor. As such, I wanted to add a firmware update which uses progmem. My understanding is that if I run from ram, I should be able to erase all sectors and update the flash. Well, I tried that and in debug I

Esp32 - sx127x support

2022-12-06 Thread Punith Condoor
Hi I am trying to integrate sx1276 based LoRa module (RFM9x), however I am unsure of any preexisting support for it. I see configuration for ttgo-lora module with sx127x example application, however did not have any luck in establishing successful link. Please advise. Thank you
