Re: Teensy 4.0 & 4.1

I have a question about your A/B firmware setup. Do you use firmware which is compiled for RAM only or do you generate two images, linked for the respective locations or have you played around with position independent code? I'm generating two XIP firmware images, one linked for the lower part of t...

Re: Teensy 4.0 & 4.1

While working on my FreeRTOS port (which is now mostly completed), I've developed my own bootloader program. The main reason was that I need the possibility to upgrade the firmware on remote location (over GSM connection to Internet). The developed bootloader provides this functionality (and works q...

Re: Teensy 4.0 & 4.1

@loboris: Do you mind if I add this script and the related Freescale executables to the Pull Request for the ARCH MIX board? You can add it, of course. The script could be improved with some more error checking and the windows version could be added, which I intend to do later this week. The script...

@loboris I made a PHY driver for the LAN8720 chip and tested it with a WaveShare LAN8720 board.
Thanks, I have the same lan board (it was used with ESP32, which has the similar issue with 50MHz clock) . I'll test it later today...

Re: Teensy 4.0 & 4.1

@Roberthh Thanks for the effort. The SomLabs carrier board is not a best example of a general purpose development board, it is more oriented to demonstrate some capabilities of the module. It is expected that the module user will develop own PCB. In that case, if using MicroPython, the new board def...

Re: Teensy 4.0 & 4.1

I just tried that on the ARC MiX board using Debian Linux. Something that puzzled me when looking at the schematics is, that GPIO_AD_B0_05 is connected to the 3/6 position of the DIP switch, not the 4/5. But the 3/6 position has to be set for QSPI boot. Setting the 4/5 position allows to download t...

Re: Teensy 4.0 & 4.1

b.t.w. Which Version of the MIMXRT1050_EVK do you have. Is it -EVK or -EVKB, nor flash or hyper flash? I think I've mentioned it in the post, I don't have MIMXRT1050_EVK, the suggested use of SW7 is only from the schematic. If you have it, you can test if the script works with hyper flash, some par...

If you like you can check out the “alpha” release of my DFU bootloader in my repository
Thanks, I'll check it.
The firmware still needs to be flashed at least the first time and my script is mostly for those who have the board but don't have J-link (which is not exactly low priced).

Re: Teensy 4.0 & 4.1

I tested more the RT1050/RT1060 serial downloader feature, and I can say it is really easy and simple to use. The firmware can be uploaded to flash without the need for J-link (or similar) programmer/debugger, just over the USB HID connection provided on practically every board (usually marked USB-O...

Re: Teensy 4.0 & 4.1

@loboris I just received the ARCH Mix board. Just a quick question: How did you load firmware to the board. My usual approach using the Ozone Debugger failed. I can connect to the board, read flash, single step. But no write. I'm working on Linux. I'm using J-link and JFlash utility to load the fir...
