## current pain
### SysTick IRQ and DMA issue
Enabling the SysTick IRQ leads to a permanent hang of the socket.
- With a 1ms interval, the hang occurs at `DHCP_ACK` during the `check_DHCP_leasedIP` -> `sendto()` ARP request.
- With a 1s interval, the hang occurs during the DNS request.
- Disabling SPI DMA solves it (just commenting out `reg_wizchip_spiburst_cbfunc`), so it's most likely DMA related?
- SPI DMA only works at SPI baud @ 8 or 64??
## ~~previous pain (DNS Processing)~~
solved by [patching](https://git.hye.su/mira/ch32-node/commit/259d63197e06c1a92b979490d4cd8f0fdb98f8d0#diff-6ba50689ba55dac7cfe3e9b011e594098c931e21) the korean bloatlib (`dns_makequery` in DNS.c)
