Invalid firmware for nxp lpcu37

VladimirAkopyan commented 7 years ago

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.

My code:

#include "mbed.h"

DigitalOut myled(LED1);

int main() {
    while(1) {
        myled = 1;
        wait(0.2);
        myled = 0;
        wait(0.2);
    }
}

My platform.ini:

[env:seeedArchGPRS]
platform = nxplpc
board = seeedArchGPRS
framework = mbed

Could you reproduce this issue with the latest development version? https://github.com/platformio/platform-nxplpc#development-version

Need to run the nwer version of the mbed libs to fix the problem with the Tickers going crazy. Current version of mbed c++ libs appears to be 150 vs the laest is 137+ framework-mbed-4.50701.0 now installed with pio update/upgrade but I think I need framework-mbed-4.50703.4. Why can't you guys use the latest?

I also see what I believe is the newer lib here: https://bintray.com/platformio/dl-packages/framework-mbed#files
