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 0x400a05e4And sometimes errors and satck trace.
Have an id what's going wrong?
Thank you for the help -
