06:07 <shenchen> i'm working on a small vexriscv+eth+sdram system with litex_sim, using stock bios and tftp booting. the demo app boots up fine, small changes to demo works too.

06:08 <shenchen> however, the instance i added eth_init() to the demo app's main(), it no longer boots.

06:10 <shenchen> what's baffling to me is that if i copy the code of eth_init() to my_eth_init() in main.c, it boots. objdump tells me that my_eth_init() and eth_init() are exactly the same in assembly code.

06:10 <shenchen> i'm wondering if there is some compile/link options i need to extend the demo app, that i overlooked?

06:11 <shenchen> TIA

16:31 <HansM> Hi, I'm am curently playing with the PCIe stuff (Xilinx VC707). I want to read/write data from the host into the DRAM. I have followed the advice in [1] to add a host AXI MMAP component and an SoC region (to be mapped into the host), but I have no clue how the host part should look like.
