Problems after flashing uLisp to an ESP32 board

#1

Hi,

The board I used is a TTGO T8 v1.7.1 with an “ESP PSRAM32H” chip (8MB). I used the Arduino IDE v1.8.19, all libraries and board updates were downloaded and installed for the IDE.
Additionally I activated the following defines in the code:
#define lisplibrary
#define lineeditor
#define vt100

Compiling/flashing was no problem and the infos given by the compiler did not indicate and shortness of the
resources.

In the Arduino IDE I choosed the
ESP32 DEV board with the following settings:
custom_CPUFreq=esp32_240
custom_CrystalFreq=generic_26
custom_DebugLevel=esp32_none
custom_EventsCore=esp32_1
custom_FlashFreq=esp32_80
custom_FlashMode=esp32_qio
custom_FlashSize=esp32_8M
custom_LoopCore=esp32_1
custom_PSRAM=esp32_enabled
custom_PartitionScheme=esp32_default

After reconnecting the board and starting a terminal program I got this endless loop:

What went wrong here? How can I fix the problem?

I think the TTGO T8 is based on the ESP32-S2 processor, which is different from the ESP32 processor supported by the current ESP version of uLisp.

I’m working on adding support for the ESP32-S2 and the next release will probably support it.

Hi David,

the TTGO T8 1.7.1 is equipped with an ESP32 DOWD08 chip.
The TTGO T8 1.8 is based on an ESP32-S2?

OK, yes it looks like your board is ESP32. However I think the problem is that the specification of your board is:

4MB Flash & 8MB PSRAM

However you’ve chosen the option:

FlashSize=esp32_8M

so I think this explains the error:

E (267) spi_flash: Detected size(4096k) smaller than the size in the binary image header(8192k). Probe failed.

Try choosing a smaller flash size setting.

Hi David,

Oh! Uuuuh…sorry. I confused flash and RAM…I fixed that and now it runs … somehow.
But this seems more a problem of the used tools:
After reflashing the board I can access it with picocom (I am using Linux).
NICE!
:)
Thanks a lot for your help!

No problem! Good to know it works on those boards.
