I want to simulate old raspberry pi 1 and 2 using qemu. * qemu-system-arm -kernel hello.exe -cpu cortex-a7 -M raspi2 -m 512 -no-reboot -serial stdio*
I use the above command to run the examples, and it does run, but not always sometimes I get this weird output's where my whole screen gets filled up with 0's. and sometimes I get an *RTEMS_FATAL_SOURCE_EXCEPTION* with *executing thread is NULL *message at the bottom. with a dump of something like this: RTEMS RPi 2B 1.1 (1GB) [00a21041] *** FATAL ** fatal source: 9 (RTEMS_FATAL_SOURCE_EXCEPTION) R0 = 0x0020e6d8 R8 = 0x00000000 R1 = 0x00000000 R9 = 0x00000001 R2 = 0x00303e10 R10 = 0x00001000 R3 = 0x00000000 R11 = 0x49444c45 R4 = 0x00000000 R12 = 0x00303c78 R5 = 0x0020e6d8 SP = 0x00300b80 R6 = 0x00000000 LR = 0x00302b1c R7 = 0x00000000 PC = 0x00204016 CPSR = 0x600001f3 VEC = 0x00000004 FPEXC = 0x40000000 FPSCR = 0x00000000 D00 = 0x0000000000000000 D01 = 0x0000000000000000 D02 = 0x0000000000000000 D03 = 0x0000000000000000 D04 = 0x0000000000000000 D05 = 0x0000000000000000 D06 = 0x0000000000000000 D07 = 0x0000000000000000 D08 = 0x0000000000000000 D09 = 0x0000000000000000 D10 = 0x0000000000000000 D11 = 0x0000000000000000 D12 = 0x0000000000000000 D13 = 0x0000000000000000 D14 = 0x0000000000000000 D15 = 0x0000000000000000 D16 = 0x0000000000000000 D17 = 0x0000000000000000 D18 = 0x0000000000000000 D19 = 0x0000000000000000 D20 = 0x0000000000000000 D21 = 0x0000000000000000 D22 = 0x0000000000000000 D23 = 0x0000000000000000 D24 = 0x0000000000000000 D25 = 0x0000000000000000 D26 = 0x0000000000000000 D27 = 0x0000000000000000 D28 = 0x0000000000000000 D29 = 0x0000000000000000 D30 = 0x0000000000000000 D31 = 0x0000000000000000 RTEMS version: 5.0.0.c6d8589bb00a9d2a5a094c68c90290df1dc44807-modified RTEMS tools: 7.5.0 20191114 (RTEMS 5, RSB 83fa79314dd87c0a8c78fd642b2cea3138be8dd6, Newlib 3e24fbf6f) executing thread ID: 0x089010001 executing thread name: I also did try running the examples on the real raspi3 but still got no luck. The steps I followed where mixture from where sources. 1. I first created a img file using objcopy. 2. Copied the kernel.img to SD card and modified the config.txt, But still it couldn't boot got no output on my serial.
