Can't figure out how to flash
Posted: Mon Oct 28, 2019 7:44 pm
Hi,
I have two boards: a WeMos ESP32-wroom, and an ESP32-SOLO-1 (marked as ESP_DevKitc_v4).
The WeMos boots and can be flashed with no issues at all.
The SOLO-1... can't figure out how to flash it.
I did modify the CONFIG_FREERTOS_UNICORE, but when I try to flash it, the result is always the same:
I tried pushing the BOOT and EN buttons, but nothing happens, no matter how or when I press them.
What's the correct way to flash 'em ?
And how can I tell if they are faulty ?
Thanks.
