# CH32V203 Node Firmware

|
||||
## current
|
||||
Firmware for a CH32V203 MCU with a W5500 Ethernet controller.
|
||||
|
||||
### SysTick IRQ and DMA issue
|
||||
[Enabling](https://git.hye.su/mira/ch32-node/src/branch/master/src/main.c#L54) the SysTick IRQ leads to a permanent hang of the socket.
|
||||
- With a 1ms IRQ interval, the hang occurs at `DHCP_ACK` during the `check_DHCP_leasedIP` -> `sendto()` [ARP request](https://git.hye.su/mira/ch32-node/src/branch/master/lib/ioLibrary_Driver/socket.c#L563).
|
||||
- With a 100ms interval, the hang occurs during the DNS request.
|
||||
- With a 1s interval it works
|
||||
- [Disabling SPI DMA](https://git.hye.su/mira/ch32-node/src/branch/master/src/w5500.c#L62) solves it (just commenting out `reg_wizchip_spiburst_cbfunc`), so it's most likely DMA related?
|
||||
- SPI DMA only works with [prescalers](https://git.hye.su/mira/ch32-node/src/branch/master/src/spi_dma.c#L140) 8 and 64?
|
||||
- Also, for some reason it needs a ~50ms delay before configuring w5500 when compiled **with** `-O0`, not needed with `-Os`...

||||
## TODO:
|
||||
UnplatformIOify this
