pico-v3-02 & psram -> reboot

Postby digiforge » Fri Nov 20, 2020 2:48 pm

Using pico-v3-02 MCU.
Installed DEV ESP32 Support into Arduino. When compiling without -DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue
resulting code is bootig and executing. Debug/Display code shows no use/existance of PSRAM as expected.
Enabling RAM during compilation (-dboard_has_psram as above) results in boot-loop

Code: Select all

rst:0xc (SW_CPU_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 271414342, SPIWP:0xee
mode:DIO, clock div:1
ho 0 tail 12 room 4
entry 0x400806a8
E (133) psram: Not a valid or known package id: 6
abort() was called at PC 0x40085653 on core 0

ELF file SHA256: 0000000000000000

Backtrace: 0x40086f48:0x3ffbba30 0x400871bd:0x3ffbba50 0x40085653:0x3ffbba70 0x400d4e81:0x3ffbbaa0 0x400d0ee8:0x3ffbbac0 0x400d0e15:0x3ffbbae0 0x400d14cf:0x3ffbbb00 0x400d3d9a:0x3ffbbb30 0x40089f2d:0x3ffbbb50

Code: Select all

esptool.py v3.0-dev
Serial port /dev/cu.SLAB_USBtoUART
Chip is ESP32-PICO-V3-02 (revision 3)
Features: WiFi, BT, Dual Core, 240MHz, Embedded Flash, Embedded PSRAM, VRef calibration in efuse, Coding Scheme None
Crystal is 40MHz
Is there similar experience with -v3-02 and Arduino IDE ?

pico-v3 is not yet supported in arduino, and I would not expect to see it supported until after the release of the next major version. Development focus is on esp32-s2 at the moment.
The code to recognize pico-v3 should be in the idf-release/v4.2 branch, but ymmv.
