I’ve been developing using the mbed online compiler for a while, and now I am doing my first test of platform.io.
I have Seed Arch GPRS V2, which is an LPC11U37 micro, programmed through USB (shows up as a flash drive). I successfully compile a blink program, when I flash the firmware, there is no effect. In fact the board goes back to bootloader, which indicated that the firmware is invalid.
I am using the .pioenvs\seeedArchGPRS\firmware.bin and flashing it onto the board. Is that the right thing to do?
At the risk of sounding like a troll, my mbed experiences have been negative.
The people are nice enough, but it seems there just aren’t enough of them. My SAMD21G18A targets used to be supported, but not now. Won’t compile with mbed OS 5.x. mbed folks say target 2.0 - a reasonable, yet disappointing solution. Going back 3.5 years in technology is not encouraging.
Your target seems not far off from that scenario.
Too bad, because the architecture is quite compelling
I mainly write this negative post as a cautionary tale that there may be only so much Ivan can do to ensure you are operational.
