I am testing Blinky for use in a high school programming class where the students have late model iPads. We are able to compile the code on the Keil studio.keil.arm.com site and download but the downloaded object file does not seem to work right when loaded oonto the LPC1768 from the iPad.
When I test it with a laptop mac the same code compiles, downloads, and runs on the target fine, so I suspect it is something in how iPad downloads from keil or how iPad loads onto target LPC1768. Any help?
How did you load/program your image file built by Keil Studio from iPad to your LPC1768 target device?
Hello. We are able to download the .bin file and then get it onto the mbed via USB cable. Today it seems not to work on both iPad and Mac - Blinky code is known to be good and the mbed is also tested and working from Linux machines.
Hello Dr E. Could you confirm a couple of things for me?First, are you using an 'On the Go' (OTG) cable to connect the LPC1768 to the iPad? This is required to transfer the binary correctly.Secondly, could you share which version of Mac OS and iPad OS you are running? There is a known issue in Mac OS Ventura that is impacting drag and drop: https://www.raspberrypi.com/news/the-ventura-problem/. This may be impacting iPad OS too. If that is the issue then I would encourage you to report the problem directly to Apple (instructions in the linked blog post). Arm is also engaging with Apple on the problem.
