Wifi_Lora_32 (v1) not working with latest 0.0.7 (flash_size 4M vs. 8M) #158

Hi, i installed v0.0.7 using Arduino Library Manager and tried to flash to a "Wifi_Lora_32" (hardware version v1 with 32MBit =4MByte Flash Chip). Flashing works but the program does not run, i get this in the Serial Monitor:

The flash_size is set to 8MB in boards.txt but the board only has 4MB, this and other settings for "wifi_lora_32.build.*" where changed before the v0.0.7 release. Should the latest version be compatible with the v1 hardware?

Workaround I

Switching back to v0.0.6 works

Workaround II

Change boards.txt in v0.0.7:

wifi_lora_32.build.flash_size=4MB
wifi_lora_32.build.partitions=default
