Interest in developer preview?

[rudi ;-)]

https://github.com/espressif/esp-idf/bl ... properties
can u please check the part "eclipse ( windows user )"


Windows users only, follow these two additional steps:

On the same Environment property page, edit the PATH environment variable and append ";C:msys32usrbin;C:msys32mingw32bin;C:msys32optxtensa-esp32-elfbin" to the end of the default value.
(If you installed msys32 to a different directory then you'll need to change these paths to match.)

Click on the "C/C++ Build" top-level properties page then uncheck "Use default build command" and enter this for the custom build command: bash ${SDK_PATH}/bin/eclipse_windows_make.sh.


EDIT:
think users wrote exact the lines ( ;C:msys32usrbin;C:msys32mingw32bin;C:msys32optxtensa-esp32-elfbin ) in environment path like they read ( i am too in first try - then have seen the format mistake )

have maked a pull request on github.
there is a small format mistake with this line:

Code: Select all

";C:\msys32\usr\bin;C:\msys32\mingw32\bin;C:\msys32\opt\xtensa-esp32-elf\bin"

change the double " at begin and at end to the right format ``
like this:

Code: Select all

``;C:\msys32\usr\bin;C:\msys32\mingw32\bin;C:\msys32\opt\xtensa-esp32-elf\bin`` 

and we read the lines right:

Okay, we released the SDK. As I said, this is just a developer preview and we don't want to create any false expectations here: please assume the code is work-in-progress and we'd appreciate it if it didn't get too much publicity yet. With that said, it gives a very good indication where we want to take the SDK.

Wit that said, the repo is at https://github.com/espressif/esp-idf , and a template project is in https://github.com/espressif/esp-idf-template . As usual, pelase point SDK_PATH to the path you downloaded esp-idf to. FYI, esp-idf stands for Espressif IoT Development Framework. We've decided not to use the SDK term anymore because esp-idf is different enough from the old esp32-rtos-sdk to warrant a new name.

As I said, we don't support anything in this version of the SDK yet. With that being said, if you do have any questions or remarks about things you think we missed, do not hesitate to ask a question here, and I'll see if I can answer it.

Looks like a nice foundation... kconfig, bootloader, MMU stuff. Anxious for features to start filling in..

have edit my post:

found little format mistake

Okay, we released the SDK. ...

kmenu, config, secure boot, aes 256 ...
very solid foundation.

and now, read in the new fresh update just in time

@espressif team
it surpasses anything - Congratulations! - the "thing" is "the hammer"
you are a hard working team!

I am ashamed - because I've bitched so impatient.


I will quietly go on foot soles now - and look forward to the release.
great best performance!

[no hurry]
not sure - search just in time a small mistake:

have changed now to the new esp-idf ( commits: 40 ..040.. )
esp-idf 040
with
esp-template 003
have noted the change of $(SDK_PATH) to $(IDF_PATH)
so:
- have changed the profile.d to the new $(IDF_PATH)


on a make in msys shell get :

Code: Select all

Makefile:10: /make/component.mk: No such file or directory
make: *** Keine Regel, um „/make/component.mk“ zu erstellen.  Schluss.
( have translate the second : ***no rule, to make „/make/component.mk“. End )

do you know where can be the mistake and what can the reason be for this?
compare just in time all changes, perhabs one old $(SDK_PATH) in one file?

edit: found 1 time in ( .gitlab-ci.yml ) $(SDK_PATH)
variables:
SDK_PATH: "$CI_PROJECT_DIR"
IDF_PATH: "$CI_PROJECT_DIR"
GIT_STRATEGY: clone

but think, this can not be the reason for the mistake.

found it
change the line in template 003 Makefile ( main )

Code: Select all

-include $(SDK_PATH)/make/component.mk
+include $(IDF_PATH)/make/component.mk

..

[rudi ;-)]

..
have seen..
.." projectgus" was faster
https://github.com/espressif/esp-idf-te ... da38561bf5

will test it later again

[rudi ;-)]

yeap.
this was the small mistake.
have used the old template 003 and have changed only the project Makefile to the new IDF_PATH
now have changed in main the Makefile too,
all ok guys!

linker missing a lib?
does we need to include in 'app' makefile the lib or does this menuconfig ( now, later ) ?

thank you in advance

[rudi ;-)]

found the small mistake in file : esp-idf components 'esp32/rom/include/aes.h

pull request is done for it
https://github.com/espressif/esp-idf/pull/3

we have in eagle.fpga32.rom.addr.v7.ld

PROVIDE ( ets_aes_crypt = 0x4005c9b8 );
PROVIDE ( ets_aes_disable = 0x4005c8f8 );
PROVIDE ( ets_aes_enable = 0x4005c8cc );

PROVIDE ( ets_aes_set_endian = 0x4005c928 );

PROVIDE ( ets_aes_setkey_dec = 0x4005c994 );
PROVIDE ( ets_aes_setkey_enc = 0x4005c97c );

to do:
change in esp-idf\components\esp32\include\rom\aes.h

the line

"ets_set_endian"

Code: Select all

void ets_set_endian(bool key_word_swap, bool key_byte_swap,\
                    bool in_word_swap, bool in_byte_swap,\
                    bool out_word_swap, bool out_byte_swap);

to

"ets_aes_set_endian"

Code: Select all

void ets_aes_set_endian(bool key_word_swap, bool key_byte_swap,\
                    bool in_word_swap, bool in_byte_swap,\
                    bool out_word_swap, bool out_byte_swap);

and we run compile & link
full app with decrypt comes asap in example code folder


for a flashing you must wait
i have no modul from ESP32 Release
