tac-tics | Just to toss a C/objdump question into the aether.... | 20:03 |
tac-tics | I am playing around with a microcontroller. I have the binary on my computer and I can upload it to the device. But I figure, maybe I'll look at the assembly and see what I can learn. | 20:03 |
tac-tics | The docs for the device say the program is loaded into memory at address 0x2040000000 | 20:04 |
tac-tics | but the disassembler says the entrypoint is at 0x20400000 (missing the last two zeros) | 20:04 |
tac-tics | That seems like it's too close to be a coincidence, so I'm sure they really mean the same address here. But I'm curious why objdump doesn't show the exact same address | 20:05 |
CarlFK | 0x20 4000 0000 vs 0x2040 0000 | 20:06 |
CarlFK | I dont trust the docs | 20:06 |
CarlFK | if that is a memory address, dos the device even have enough memory for 0x20 4000 0000 ? | 20:07 |
tac-tics | Oh. I misread. | 20:07 |
tac-tics | Indeed. The bootloader is at 0x2000_0000 | 20:07 |
tac-tics | fuck | 20:07 |
tac-tics | Indeed. The bootloader is at 0x2000000000 | 20:08 |
tac-tics | maybe it is a typo in the docs too. I should sanity check | 20:08 |
mithro | Morning everyone | 20:08 |
mithro | cr1901_modern: morning | 20:09 |
tac-tics | morning | 20:09 |
tac-tics | The memory map only goes up to 0xffff_ffff | 20:10 |
tac-tics | So maybe it is a typo | 20:10 |
tac-tics | And yeah, since it's a 32-bit processor, I think that original address is too big anyway | 20:11 |
tac-tics | Does "on-chip" vs "off-chip" refer to memory that is embedded in the CPU vs on some other IC on the same board? | 20:16 |
CarlFK | mithro: are you in.. where are you? | 20:17 |
tac-tics | CarlFK, where aren't I? | 20:18 |
mithro | CarlFK: I fly to Poland on Wednesday | 20:18 |

tac-tics | and now you want me to download a thing | 21:57 |
tac-tics | you're asking me too many download a thing, manaaan | 21:57 |
tac-tics | wtf is this. It says it's done, but then there's no "Quit" or "Close" afterwards.. | 22:00 |
tac-tics | alright, it's stilled | 22:01 |
tac-tics | what do I do now | 22:01 |
CarlFK | verify the licence please | 22:01 |
CarlFK | or say "what license" | 22:01 |
