| mithro | AmosSam: the Tomu does have very limited ram resources | 06:56 |
|---|---|---|
| mithro | AmosSam: the Fomu has a *lot* more space | 06:57 |
| AmosSam | I knew that, but I was hoping anyway... | 06:57 |
| mithro | AmosSam: you should make sure that all code is ending up in the flash section | 06:57 |
| AmosSam | Well, what I could see (and understand), it does... map file sizes/addresses add up corectly... | 06:59 |

| mithro | Wood Tomu programmer! https://usercontent.irccloud-cdn.com/file/RLxrawX2/image.png | 07:31 |
| xobs | AmosSam: you can make sure stuff goes in flash by marking it "const", which will free it from RAM. | 07:33 |
| xobs | mithro: Woo! | 07:33 |
| AmosSam | xobs: but then variable is constant, immutable? | 07:38 |
| xobs | AmosSam: correct. so you'd do that for things like private and public keys, which are large and don't ever change. | 07:38 |
| AmosSam | xobs: hmm, so another look on code... but gnuk uses "flash" storage for keys, because you can change them without reflashing fw. Thx for hint | 07:41 |
| mithro | xobs: I think the CSRs were also broken at width greater than 8bits | 08:01 |
| mithro | xobs: Looking at your comment - it's likely to do with the sys clock multiple weirdness | 08:09 |
| xobs | mithro: quite possibly. | 08:12 |
| xobs | my bodge to update CSRStorage seems to be working at least. | 08:12 |
| mithro | xobs: Did you see Luke's questions around the USB stuff... | 08:14 |
| mithro | (On twitter) | 08:14 |
| xobs | mithro: no, where are they? | 08:14 |

| AmosSam_ | me again... is it possible to flash on tomu firmware with file size of 58376 bytes? I suppose i need to overwrite bootloader? | 19:44 |
| AmosSam_ | with stlink and openocd, yes... | 21:05 |

| mithro | xobs: that is enough you can probably start testing on hardware | 23:31 |
| mithro | xobs: I would recommend doing that sooner rather than later | 23:32 |
| mithro | xobs: the epmem interface hasn't been tested on hardware in any way... | 23:32 |
