Constant rebooting

I flashed a device, ESP32, and it constantly reboots, thus:

The line "CForth build Undefined word encountered" means that something went wrong in the compilation phase. Without knowing a lot more about what you tried, I can't debug further. I need to know which version of the cforth tree you are using, which build directory you are working in, what system you are compiling on, and any modifications that you have made.
I tried again, now this :
E (64) boot: Chip CPU frequency rated for 160MHz. Modify CPU frequency in menuconfig

E (64) boot: Chip CPU frequency rated for 160MHz. Modify CPU frequency in menuconfig

it is: cforth WIP: built in build/ESP32: compiled on a linux box: no changes: device is ESP32-WROOM-32
I did successfully install on a "HiGrow" device which has the same chip.
The error implies a CPU frequency error and correcting with menuconfig ... but where is menuconfig?
menuconfig is a tool that the ESP IDF development environment uses to modify the sdkconfig file, which sets up a lot (more than 700) configuration parameters that control how the application is built. The easiest way to solve the 160 MHz problem is to edit build/esp32/sdk_build/sdkconfig directly. Change these lines:
CONFIG_ESP32_DEFAULT_CPU_FREQ_160=
CONFIG_ESP32_DEFAULT_CPU_FREQ_240=y
CONFIG_ESP32_DEFAULT_CPU_FREQ_MHZ=240
to
CONFIG_ESP32_DEFAULT_CPU_FREQ_160=y
CONFIG_ESP32_DEFAULT_CPU_FREQ_240=
CONFIG_ESP32_DEFAULT_CPU_FREQ_MHZ=160
I added a target to the makefile so you can say
make menuconfig
in cforth/build/esp32 . It might work for you, but it is a complicated process to compile it, so if something goes wrong, I really don't have time to support it. I can support direct edits of sdkconfig.
I simply edited the sdkconfig file. All is working.
Next challenge is to discover how to drive io pins , ADC etc and wifi
Thanks
