| Shatur | Hi! I generated svd and memory from litex_sim, but have the following linker error: section '.text.dummy' will not fit in region 'spiflash': overflowed by 18446744073675997184 bytes | 06:54 |
|---|---|---|
| Shatur | Is that too many bytes? Does this mean that the generated memory and svd are invalid? | 06:55 |
| geertu | Shatur: 18446744073675997184 = 0xFFFFFFFFFE000000 = -0x2000000 | 07:29 |
| Shatur | Yes, looks like an overflow? | 07:30 |
| geertu | Shatur: Any chance the llinker script has some symbols in the wrong order? | 07:45 |
| Shatur | geertu: here is how my memory.x look: https://pastebin.com/N6mCQskr | 07:46 |
| tpb | Title: memory.x - Pastebin.com (at pastebin.com) | 07:46 |
| Shatur | I use rust | 07:46 |
| geertu | Shatur: There's no spiflash under MEMORY? Perhaps you meant rom? | 07:48 |
| Shatur | geertu: oh, sorry, it's a wrong file with my experiments :) Here is the right one: https://pastebin.com/MBFcfBNZ | 07:51 |
| tpb | Title: memory.x - Pastebin.com (at pastebin.com) | 07:51 |
| geertu | Shatur: Change _stext to 0x01000000? | 07:53 |
| geertu | Currently, it's at -32 MiB from the end of spiflash | 07:53 |
| geertu | Hmm, as it is CPU reset, it should stay at zero. | 07:54 |
| geertu | But you should make sure it ends up in rom, not in spiflash. | 07:54 |
| Shatur | geertu: it worked, thank you! | 07:56 |
| Shatur | But why litex_sim generates it this way? Is it a bug? | 07:56 |
| Shatur | Here is what I used to generate it: litex_sim --csr-svd=hal/litex_sim_pac/soc.svd --memory-x=hal/litex_sim_pac/memory.x --with-spi-flash | 08:04 |
| geertu | Shatur: sorry, no idea | 08:11 |

| Shatur | Is it possible to connect to litex_sim via serial? I trying to print something via UART. | 09:53 |
| Shatur | In simulator it shows --============= Liftoff! ===============-- and nothing after it. Is it something wrong with the firmware or I just need to connect to the simulator somehow? | 10:00 |
| Shatur | Oh, I see, it prints UART to console by default using uart2console module. Probably something wrong with printing code. | 10:42 |
