MBED crash - RP2040 rebooting #1

Closed Gerriko closed 3 years ago

Gerriko commented 3 years ago

This is the output from Serial (it happens with both examples): Start LittleFS_Counting on RaspberryPi Pico LittleFS_Mbed_RP2040 v1.0.0 [LFS] LittleFS size (KB) = 256 [LFS] LittleFS Mount Fail [LFS] Formatting...

You then see the standard LED blink (5 short and some long blinks) which is associated with an MBED failure.

If you then open up a separate Serial output on Serial1 you get the mbed debug info:

Strange. There must be some breaking change from core v2.1.0 (I tested and created the library then).

Can you try with core v2.1.0? I'll spend time later to find out why and fix the issue.

khoih-prog commented 3 years ago

Confirmed. Got the same crash as you did with core v2.4.1 now.

khoih-prog commented 3 years ago

Try smaller flash size => OK.

So might be the code size is much bigger now => 256K LittleFS can't be used. Or might be using new address for flash start. I'll see. Please change :

#define RP2040_FS_SIZE_KB       64    //256

khoih-prog commented 3 years ago

Try 128K still crashing. So please use 64K from now on until the issue found and fixed.

khoih-prog commented 3 years ago

Testing again with 256K LittleFS

Core v2.1.0 => OK
Core v2.2.0 => OK
Core v2.3.1 => OK
Core v2.4.1 => OK now !!! After installing v2.1.0, ..., then back to v2.4.1.

Very strange, possibly some flags is not written correctly. Will see.

In the mean time, please try with v2.1.0, then v2.4.1 to see if OK.

Don't have issue with another RP2040 board with core v2.4.1 at the beginning. So it's somehow board dependent !!! This is difficult to find out where the issue is.

Any idea???

khoih-prog commented 3 years ago

The other example LittleFS_Counting => still OK with 256KB

Start LittleFS_Counting on RaspberryPi Pico
LittleFS_Mbed_RP2040 v1.0.0
[LFS] LittleFS size (KB) = 256
[LFS] LittleFS Mount OK
Times have been run = 1
 => Open to write OK

Start LittleFS_Counting on RaspberryPi Pico
LittleFS_Mbed_RP2040 v1.0.0
[LFS] LittleFS size (KB) = 256
[LFS] LittleFS Mount OK
 => Open to read OK
Times have been run = 2
 => Open to write OK

Start LittleFS_Counting on RaspberryPi Pico
LittleFS_Mbed_RP2040 v1.0.0
[LFS] LittleFS size (KB) = 256
[LFS] LittleFS Mount OK
 => Open to read OK
Times have been run = 3
 => Open to write OK

Start LittleFS_Counting on RaspberryPi Pico
LittleFS_Mbed_RP2040 v1.0.0
[LFS] LittleFS size (KB) = 256
[LFS] LittleFS Mount OK
 => Open to read OK
Times have been run = 4
 => Open to write OK

khoih-prog commented 3 years ago

I'm closing the issue now as it seems this is not a bug of the library.

Gerriko commented 3 years ago

Agree. It seems to be board related. Have it working.
