+### Important Notes for Portenta_H7
+
+The LittleFS of the new **Portenta_H7** board currently tested OK with only **maximum 8 files**. The files, from 9 and up, somehow strangely can't be written and / or read. This is possibly a bug in the [`ArduinoCore-mbed mbed_portenta core`](https://github.com/arduino/ArduinoCore-mbed). The same behaviour is observed from core v2.0.0 up to v2.4.1.
+
+If LittleFS size is reduced to 1024KB, test is OK with only **maximum 4 files**.
+
+Beware and keep cheking for updates.

-### Releases v1.0.1
-
-1. Change the default and minimum LITTLEFS_PORTENTA_H7_SIZE_KB to 1024KB, instead at maximum available size. This is done to avoid the cases where the code size is larger, and LittleFS size has to be changed, reformatted, leading to data loss.

+### Releases v1.0.2
+
+1. Back to using auto LittleFS size to fix bug and to permit 8 LittleFS files instead of 4 in previous release. There is a bug somewhere in the [`ArduinoCore-mbed mbed_portenta core`](https://github.com/arduino/ArduinoCore-mbed) and we have to live with it.
