success using the bluepill as the daplink! one thing i had to do in order to get the rt1052 to respond within mcuxpresso was have it plugged into the bluepill when placing the stm32f103xb_mimxrt1050_qspi_if.bin onto the Maintenance bluepill drive. Then it loaded and i was able to flash using this method!

Seems like the default ip address is set to 10.10.10.10 with the current repo config, is that correct? I was going to test against the device to see if it responded to pings

Great to hear you are up and going! Yes, the IP address is 10.10.10.10 but as you are compiling from source you could change that if needed.

I'll get the additional IO for the EC500 worked out over the next week or so.

Another data point. For giggles, I tried using a bluepill board as a target and that did work as expected! It mounted as Maintenance, then placed the _if.bin on there and reset and remounted as RT1052. mcuexpresso with the bluepill detects the daplink.

Yet now the pin mapping you gave in forum.linuxcnc.org/18-computer/44828-rem...ard?start=590#262786 I am not having success with.

ive shorted PB12 and PB14 via 100ohm resistor but still doesnt detect the board when attempting to connect in mcuxpresso. Is there anything on the board side you need to do to trigger the programming?

I have connected the SWD,SCK,3.3v and G on the EC500 board to the bluepill as such:

ec500

---

blue pill

Code:

3.3 ------------ 3.3 G ------------ G SCK ---------- PB13 SDO ---------- PB14

The EC500 has a 3.3v pin on the header but my ST-Link could not power the board reliably. No issues connecting when using powering the board with 24v and only connecting the 3 pins (G, SCK SWDIO).

Still cant move ion from Maintenance step, 2nd bin file fails with this output:
error: The transfer timed out.
type: transient, user

I have tried 4 different ST Links now and 2 different Windows systems to rule out anti virus.

With the issues people are having with the DAPLink, I've added the CMSIS-DAP probe firmware for the ST-Link V2 to the dev repo. This is the firmware I've used for all the development work on the RT1052.

github.com/scottalford75/Remora-RT1052/b...SIS-DAP-STLINK21.hex

At least people will be able to flash the board from MCUXpresso.

I will get MCUXpresso installed tomorrow and give it a go, thank you!

Wondering if this is possibly a driver issue?
My latest attempt and the bin file just sat there on the STLink, if I eject and remount it the bin file (as expected) disappears and volume continues to be called maintenance, and the htm file does not change either.
