Incompatiblity of esp32ulp_build_receipe.py with recent 2.0.6 esp32 release

[christianpaetz]

The paths to sdkconfig have changed and the RESERVE_MEM name too.

line 174: file_path = os.path.join(PATHS['core'], 'tools', 'sdk', 'esp32', 'qio_qspi', 'include', 'sdkconfig.h' )
line 176: mem = re.findall(r'#define CONFIG_ESP32_ULP_COPROC_RESERVE_MEM (.*?)\n', text)[0]
line 270: sdk_hash = md5(os.path.join(PATHS['core'] , 'tools', 'sdk', 'esp32','qio_qspi','include', 'sdkconfig.h'))

assuming 'qio' is selected.

Unfortunately larger .S files still create a problem and will not start. No idea why.

Hi!

Do you know if esp core 2.0.6 is working? And ESP32 S2? Thanks

Works with 2.0.6, No idea aboutS2

[Andermutu]

I finally managed to make it work with ESP32 S2!

[aqua-scope]

can you publish the diff to make a change request please

I managed to make it work with ESP32 S2. I can compile and run examples ulp_readme example and a digital input counter example. They work fine unless the main cpu enters deep sleep. In the moment the main cpu enters deep sleep, ULP stops running for some reason:

@Andermutu Hello! Do you solve a problem with ULP? I'll be glad if you share you solution. I also can help if needed.
I need run ULP code with Arduino framework. I want to move my project @waterius to ESP32S2
