esptool for esp32, make app problem (ESPTOOL-836)

Thanks for reporting this. It seems like there's two bugs here, esptool shouldn't be printing such an enormous stack trace for "IOError: [Errno 2] No such file or directory: '/home/michal/esp32/myapp/build/app-template.elf"

Then there's what looks like it might be an esp-idf bug, the ELF file doesn't exist at the time elf2image is being called.

Can you please run 'make V=1' and attach the output as a log file to a comment here (or post it on gist.github.com or another service)?

Thanks. I didn't think through my request properly, you can do a 'make clean' and then 'make V=1' and update the log with that output? Thanks.

Something very odd is happening here:

This line should link a bootloader ELF, output to /home/michal/esp32/myapp/build/bootloader/bootloader.elf

xtensa-esp32-elf-gcc -nostdlib -L/home/michal/esp32/myapp/build/bootloader/esptool_py -L/home/michal/esp32/myapp/build/bootloader/bootloader -L/home/michal/esp32/myapp/build/bootloader/bootloader_support -L/home/michal/esp32/myapp/build/bootloader/log -L/home/michal/esp32/myapp/build/bootloader/spi_flash -L/home/michal/esp32/myapp/build/bootloader/micro-ecc -L/home/michal/esp32/myapp/build/bootloader/main -u call_user_start_cpu0  -Wl,--gc-sections -Wl,-static -Wl,--start-group  -lbootloader_support -llog -lspi_flash -lmicro-ecc -L /home/michal/esp32/esp-idf/components/bootloader/src/main -lmain -T esp32.bootloader.ld -T /home/michal/esp32/esp-idf/components/esp32/ld/esp32.rom.ld -lgcc -Wl,--end-group -Wl,-EL -o /home/michal/esp32/myapp/build/bootloader/bootloader.elf -Wl,-Map=/home/michal/esp32/myapp/build/bootloader/bootloader.map

It seems to succeed, and then the very next line refers to the same ELF file path:

python /home/michal/esp32/esp-idf/components/esptool_py/esptool/esptool.py --chip esp32 elf2image --flash_mode "dio" --flash_freq "40m" --flash_size "16MB"  -o /home/michal/esp32/myapp/build/bootloader/bootloader.bin /home/michal/esp32/myapp/build/bootloader/bootloader.elf

Which causes an error because the file doesn't exist.

• Does the build/bootloader directory exist?
• Can you find a bootloader.elf anywhere in your build directory?
• What toolchain are you using and how did you compile/install it?
• Is there anything in /home/michal/esp32/myapp/build/bootloader/bootloader.map

Very unusual, but I'm glad you got it working OK.
