Build firmware for external spiram

[davidbogatec]

I have a problem with building the micropython firmware for generic spiram.
I need to build it for ESP32 VROVER module that has 4 MB of additional spiram and have also to integrate custom C-User module.
How to do? thanks

Hi,
What's the issue you're seeing? What have you tried so far?

Hi Jimmo,
when I try to build it with

Code: Select all

make BOARD=GENERIC_SPIRAM

the build stops with the following output.


Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.

make: *** [Makefile:954: build-GENERIC_SPIRAM/bootloader//home/bogatec/esp32/esp-idf/components/bootloader_support/src/bootloader_clock.o] Error 1

any idea?
thanks for your support

Which toolchain are you using? How did you set it up?

[davidbogatec]

Here the info you've requested

I am working in linux environment.
I am using the same setup, toolchain, to build normal or spiram enabled firmware. I succeed to build the generic firmware but not the spiram.

What I do:
1) Download and extract xtensa-esp32-elf-linux64-1.22.0-61-gab8375a-5.2.0.tar.gz
wget https://dl.espressif.com/dl/xtensa-esp3 ... 2.0.tar.gz
tar -xzf xtensa-esp32-elf-linux64-1.22.0-61-gab8375a-5.2.0.tar.gz
export PATH=$PATH:$HOME/esp32/xtensa-esp32-elf/bin
echo "export PATH=\$PATH:$HOME/esp32/xtensa-esp32-elf/bin" >> ~/.bashrc

2) micropython$ make -C mpy-cross
3) create makefile in ports/esp32

ESPIDF = /home/sviluppo/Micropython/esp32/esp-idf
#PORT = /dev/ttyUSB0
#FLASH_MODE = qio
#FLASH_SIZE = 4MB
#CROSS_COMPILE = xtensa-esp32-elf-
include Makefile

What is wrong in your opinion?

Thank Jimmo

Hi,

What is wrong in your opinion?

Sorry about the delay... I was hoping someone else would know because I'm a bit stumped ...

I mostly use IDF 4.0 and the new 8.2 toolchain, but I went back and did a test build with the old 5.2 toolchain and IDF 3.3.1. (Building at the current micropython master --1993c8cf9af930cd6ff2f28390ac3a8a09d5b297 ).

Code: Select all

$ export PATH=/home/jimmo/src/github.com/espressif/toolchain/xtensa-esp32-elf/bin:$PATH

$ (cd /home/jimmo/src/github.com/espressif/esp-idf3 && git describe && git rev-parse HEAD)
v3.3.1
143d26aa49df524e10fb8e41a71d12e731b9b71d

$ xtensa-esp32-elf-gcc --version
xtensa-esp32-elf-gcc (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a) 5.2.0

$ blaze BOARD=GENERIC_SPIRAM clean
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
Building with ESP IDF v3
rm -rf build-GENERIC_SPIRAM

$ blaze BOARD=GENERIC_SPIRAM
(success)

So I guess the first thing to check is that you have the same xtensa-esp32-elf-gcc --version and IDF commit hash.

Then then next thing might be to try using the new toolchain (8.2.0) which you can install using the IDF 4.0 (I just updated the instructions for this today -- see https://github.com/micropython/micropyt ... 5713/files )
