Description
Since LVGL was “crashing” due to the fact that my LV_MEM_SIZE was too small I tried increasing this size by moving the memory buffer for LVGL.
But now all I get is the following.
[Error] (0.310, +310) insert_free_block: Asserted at expression: current && “free list cannot have a null entry” (in lv_tlsf.c line #614)
My original memory map looked like this
+------------ 0x20003900 ------------+
| eventrecorder (1280 bytes) |
+------------ 0x20003E00 ------------+
| |
+------------ 0x20004100 ------------+
| LVGL memory (16128 bytes) |
+============ 0x20008000 ============+
| Controller internal |
+============ 0xA0000000 ============+
And, by removing the eventrecorder (part of the keil uVision) my new memory map should look like this.
+------------ 0x20003900 ------------+
| LVGL memory (18176 bytes) |
+============ 0x20008000 ============+
| Controller internal |
+============ 0xA0000000 ============+
And lv_conf (original)

What MCU/Processor/Board and compiler are you using?
An LPC1788 with keil uVision and LVGL 8.4.0 (was 8.3.11)
What do you want to achieve?
A bigger LV_MEM_SIZE
What have you tried so far?
Nothing really, I just changed my LV_MEM_SIZE and LV_MEM_ADR, next I know 2 of the asserts where failing.
The 1st was
tlsf_assert(block_to_ptr(block) == align_ptr(block_to_ptr(block), ALIGN_SIZE)
&& "block not aligned properly");
Next the current assert is also failing
tlsf_assert(current && "free list cannot have a null entry");
Code to reproduce
No real steps required. I have the LV_USE_MEM_MONITOR enabled so I can keep tabs on the memory usage. But when I now start the LVGL thread the memory monitor only displays a ? followed by a assert crash at the above mentioned locations.
