1218: Lora: sx126x: Change timing window to match values found experimentally. r=Dirbaio a=CBJamo
As mentioned in #1188.
1219: stm32/sdmmc: Fix SDIOv1 writes r=Dirbaio a=chemicstry
This fixes writes on sdmmc v1 (SDIO). I'm pretty sure I tested writes in #669, but maybe I was just lucky or I just forgot.
There were two problems:
- Writes require DMA FIFO mode, otherwise SDIO FIFO is under/overrun depending on sdio/pclk2 clock ratio.
- Hardware flow control is broken for sdmmc v1 (I checked F1 and F4 erratas). This causes clock glitches above 12 MHz and results in write CRC errors.
