Build failure on OSX and Linux64

[jeremyherbert]

When building for LoPy: make BOARD=LOPY LORA_BAND=USE_BAND_915 TARGET=app

I needed to do this first: micropython/micropython@326343f

[jeremyherbert]

I'm now stuck at this error:

make: *** [build/LOPY_915/release/mods/machtimer_alarm.o] Error 1

[jeremyherbert]

Also fails on Ubuntu 16.04 with the same error.

[jeremyherbert]

I also note that the travis build is broken

[jeremyherbert]

It looks like the esp32 compiler listed in the readme might be the problem here. On further inspection of the pycom-esp-idf, I am getting errors about incorrect compiler versions. I'm building the latest compiler now.

[jeremyherbert]

Ok, looks like I'm almost there. I had to:

1. build mpy-cross as earlier
2. Ignore the toolchain in the readme, it has a bug in the compiler which has since been fixed. Go with this: http://esp-idf.readthedocs.io/en/latest/get-started/linux-setup-scratch.html
3. The correct build command for the bootloader is make BOARD=LOPY LORA_BAND=USE_BAND_915 TARGET=boot (readme is missing the LORA_BAND part
4. make flash requires pyserial to be installed and access to the usb serial port on the current user. sudo doesn't appear to work

After all of this I was able to build and flash the device. However my LoPy no longer boots. Still working on that one. I just get:

rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
ets Jun  8 2016 00:22:57

load:0x4009fc00,len:848
entry 0x4009fd9c

and then nothing

[jeremyherbert]

Looks like the bootloader is toast. If I reflash the pycom provided image and then flash my own appimg.bin on top of that, it appears to work

[jeremyherbert]

FWIW if anyone else is ever struggling with this, the flash command is

python tools/esptool.py write_flash 0x10000 build/LOPY_915/release/appimg.bin

run it from the esp32 folder.

[yelsherbini]

I had the same error but I followed someone's suggestion in the forum to download a newer toolchain version: https://dl.espressif.com/dl/xtensa-esp32-elf-osx-1.22.0-61-gab8375a-5.2.0.tar.gz . It worked perfectly. I am using OSX btw

I am using the WIPY 2.0 and need to use the newest compiler as @Yahia13 pointed out to get my application compiled. After compiling with make BOARD=WIPY TARGET=app and flashing with make BOARD=WIPY flash the board hangs at entry 0x4009fd9c like the LOPY of @jeremyherbert. Using python tools/esptool.py write_flash 0x10000 build/WIPY/release/appimg.bin fixes the problem.

[jeremyherbert]

For what it's worth, I found out the answer to this. The correct way to flash is:

#!/bin/sh
python esptool.py --after no_reset -b 921600 erase_region 0x1000 0x40000
python esptool.py --after no_reset -b 921600 erase_region 0x41000 0x40000
python esptool.py --after no_reset -b 921600 erase_region 0x81000 0x40000
python esptool.py --after no_reset -b 921600 erase_region 0xC1000 0x40000
python esptool.py --after no_reset -b 921600 erase_region 0x101000 0x40000
python esptool.py --after no_reset -b 921600 erase_region 0x141000 0x40000
python esptool.py --after no_reset -b 921600 erase_region 0x181000 0x40000
python esptool.py --after no_reset -b 921600 erase_region 0x1C1000 0x40000

python esptool.py --after no_reset -b 921600 write_flash 0x1000 bootloader.bin
python esptool.py --after no_reset -b 921600 write_flash 0x8000 partitions.bin
python esptool.py --after no_reset -b 921600 write_flash 0x10000 lopy_915.bin

bootloader.bin, lopy_915.bin and partitions.bin come from your build directory.

[nevercast]

Why is it the correct way to erase in blocks of 262k ? Why not use erase_flash ?

My current command is:

esptool.py write_flash -z --flash_mode qio --flash_freq 40m --flash_size 4MB --after hard_reset --chip esp32 --port ${COM} --baud 921600 0x1000 ${BOOT} 0x8000 ${PART} 0x10000 ${APP}

This is done after an erase_flash which blanks the entire flash. If there is something ill practice about this I'd like to know about it.

Kind regards,
Josh.

[jeremyherbert]

I should have been clearer: that is the way that the pycom updater tool does it. I just traced and dumped the commands from there. I am not privy to the reasoning.

[nevercast]

I did try OTA before trying to flash via USB/serial. Could #81 be related to this issue? (Bootloader not working)

Edit: @jeremyherbert It just occurred to me that one reason to erase in blocks like that is for a progress bar, does the official flash tool provide a progress?
