Dear @iabdalkader and @kwagyeman,
I updated firmware using DFU (as suggested @kwagyeman):
(tensorflow)sholc:util$ python pydfu.py -u ../../firmware/firmware.dfu
File: ../../firmware/firmware.dfu
DfuSe v1, image size: 936137, targets: 1
Target 0, alt setting: 0, name: "ST...", size: 935852, elements: 2
0, address: 0x08000000, size: 65536
1, address: 0x08010000, size: 870300
usb: 0483:df11, device: 0x0000, dfu: 0x011a, UFD, 16, 0xc9f97f07
Writing memory...
0x08000000 65536 [=========================] 100%
0x08010000 870300 [=========================] 100%
Exiting DFU...
and updated Openmv using Bootloader (on openmv.bin). In both cases images uploaded successfully and blue nice blinking. After ~ 30 sec red light turning on and blue continue to blinking.
Also previous issue with connecting in the IDE is actual for me
fw_version:(1919117645, 2035294319, 1852794996)
ide_version:(1, 5, 0)
That is interesting after updating using bootloader in the internal storage I so four files in the root:
sholc:2989-0800$ ls -l
total 7
-rw-r--r-- 1 sholc sholc 247 dec 9 2000 main.py
-rw-r--r-- 1 sholc sholc 2429 dec 9 2000 openmv.inf
-rw-r--r-- 1 sholc sholc 551 dec 9 2000 README.txt
-rw-r--r-- 1 sholc sholc 2217 dec 9 2000 selftest.py
but after OpenMV reconnection only three:
total 4
-rw-r--r-- 1 sholc sholc 247 dec 9 2000 main.py
-rw-r--r-- 1 sholc sholc 2429 dec 9 2000 openmv.inf
