| octavius | Just to make sure I'm not being dumb here, this error is indicating that I don't have enough memory for this Microwatt binary, right? | 19:52 |
| octavius | powerpc64le-linux-gnu-ld -T powerpc.lds -o hello_world2.elf hello_world2.o head.o console.o memory_mw.o sha256.o | 19:52 |
| octavius | powerpc64le-linux-gnu-ld: section .data.init_msg LMA [0000000000001800,000000000000181d] overlaps section .text.sha256_final LMA [00000000000017b0,0000000000001927] | 19:52 |
| octavius | make: *** [Makefile:31: hello_world2.elf] Error 1 | 19:52 |
| programmerjake | seems like a reasonable guess, though note that it's microwatt cpu's accessible memory, not your host computer's memory | 19:56 |
| octavius | Yeah, I thought so. Currently looking through the microwatt/ls2 files to see where the amount of memory can be increased | 19:58 |

| programmerjake | idk if it's different when building to use with libre-soc, but when I built microwatt for my 3d maze game, it was a Makefile variable | 20:00 |
| octavius | Yeah, I found the variable for the HDL. | 20:01 |
| programmerjake | I used make ... MEMORY_SIZE=$((1<<18)) | 20:01 |
| octavius | Thanks | 20:01 |
| programmerjake | though 1 << 18 may be too big for you | 20:02 |
| octavius | In this case, I'm looking at where the parameter for the binary compilation is. Found the file powerpc.lds | 20:02 |
| octavius | _start = .; | 20:02 |
| octavius | . = 0; | 20:02 |
| octavius | .head : { | 20:02 |
| octavius | KEEP(*(.head)) | 20:02 |
| octavius | } | 20:02 |
| octavius | . = 0x1000; | 20:02 |
| octavius | .text : { *(.text) } | 20:02 |
| octavius | . = 0x1800; | 20:02 |
| octavius | .data : { *(.data) } | 20:02 |
| octavius | .bss : { *(.bss) } | 20:02 |
| octavius | It complained about the .text and .data overlapping | 20:03 |

| programmerjake | ah, yeah, if you increase the memory size, you can have the .data start later | 20:03 |
| octavius | Thanks! | 20:04 |
| programmerjake | e.g. if the memory size is 1<<15 (32kiB) then .data can start at 0x4000 -- halfway through the ram | 20:05 |
| octavius | I moved from 0x1800 to 0x2800, that seemed to be enough, generating bitstream now | 20:09 |
| programmerjake | you may also have to adjust STACK_TOP in head.S, assuming it's like the code i used | 20:13 |
| octavius | The only change I made was to powerpc.lds file, and didn't rebuild the HDL, so hopefully this is good enough for now | 20:15 |
| octavius | But yeah, will need to do more | 20:15 |
