Cant start after flash



  • Hello,
    I just buy a fipy, but no extension board.
    I try to flash the firmware with a serial converter as explained here, https://github.com/pycom/pycom-documentation/blob/master/getting-started/hardwaresetup/fipy.md with the update software.
    Flash succeed, but if I try to boot the device I only have this on serial connection:

    ets Jun  8 2016 00:22:57
    
    rst:0x1 (POWERON_RESET),boot:0x12 (SPI_FAST_FLASH_BOOT)
    configsip: 0, SPIWP:0xee
    clk_drv:0x00,q_drv:0x00,d_drv:0x00,cs0_drv:0x00,hd_drv:0x00,wp_drv:0x00
    mode:DIO, clock div:1
    load:0x3fff8028,len:8
    load:0x3fff8030,len:1984
    load:0x4009fa00,len:0
    load:0x4009fa00,len:19088
    entry 0x400a05e4
    

    And sometimes errors and satck trace.
    Have an id what's going wrong?
    Thank you for the help



  • Ok solved using 5v as vcc nor 3.3v for the boot
