Known Issues

  • RA0E1:

    • e2 studio projects automatically reset compiler optimization to a Size setting on every generate or build operation
    • Add optimization flags (e.g. -O0) manually to 'Other optimization flags' to override the -Oz setting
    • HS400x, ZMOD4xxx, and OB1203 sensors cannot be used on RA0E1
