We briefly discussed this off list, what is likely happen is that our heap is after 0xFFFFFFFF, or said in a simpler way in the 64-bit address space, while ram top is at the 4GB boundary. The solution seems to either move the heap down or move ram top up. > > U-Boot 2025.01-rc4-00025-g4ff8ecd9b14e-dirty (Dec 16 2024 - 11:21:18 -0300) > > CPU: Freescale i.MX8MP[8] rev1.1 1600 MHz (running at 1200 MHz) > CPU: Industrial temperature grade (-40C to 105C) at 51C > Reset cause: POR > DRAM: Ram top: FFFFFFFF > 8 GiB > ... > Verdin iMX8MP # bdinfo > boot_params = 0x0000000000000000 > DRAM bank = 0x0000000000000000 > -> start = 0x0000000040000000 > -> size = 0x00000000c0000000 > DRAM bank = 0x0000000000000001 > -> start = 0x0000000100000000 > -> size = 0x0000000140000000 > flashstart = 0x0000000000000000 > flashsize = 0x0000000000000000 > flashoffset = 0x0000000000000000 > baudrate = 115200 bps > relocaddr = 0x00000000ffece000 > reloc off = 0x00000000bfcce000 > Build = 64-bit > current eth = ethernet@30bf0000 > ethaddr = 6e:79:12:b6:72:24 > IP addr = <NULL> > fdt_blob = 0x00000000ffab8450 > lmb_dump_all: > memory.count = 0x1 > memory[0] [0x40000000-0x23fffffff], 0x200000000 bytes, flags: none > reserved.count = 0x1 > reserved[0] [0xffffffff-0x23fffffff], 0x140000001 bytes, flags: > no-overwrite > devicetree = separate > arch_number = 0x0000000000000000 > TLB addr = 0x00000000fffd0000 > irq_sp = 0x00000000ffab8440 > sp start = 0x00000000ffab8440 > Early malloc usage: d620 / 10000 > > > Best Regards, > João Paulo Gonçalves
