This page describes all changes made to the usbh_drv_atmel package, USB Atmel Host Controller, since its release.
2.13 (2019-03-11, 17:10):
- Several bugs fixed in Fair access pipe implementation and it was made interrupt safe.
- Wrong interrupt handling fixed if multiple endpoint interrupts are fired.
- Wrong interrupt handling fixed if multiple DMA interrupts are fired.
- Bit handling in usbh_atmel_used_hw_pipe() is fixed.
- SOF interrupt is only enabled if at least to transfers were added to bulk FIFO.
2.12r2 (2018-08-29, 18:13):
- Document HTML link added to the documentation folder.
- History and document files renamed to the package name.
2.12 (2018-04-11, 18:26):
- Build error removed for the case USBH_ATMEL_BULK_SOF_SCHEDULE == 0.
- Compiler warnings eliminated.
2.11 (2017-09-19, 12:09):
- Last packet of a multi-packet transmission might have been delayed until the next transmission on the same endpoint.
- Jittering USB data lines during USB reset could lock up the driver.
- Interrupt load could have been unreasonably increased if multiple bulk endpoints are used and USBH_ATMEL_BULK_SOF_SCHEDULE is enabled.
- Double buffer operation did not reflect user configuration.
- First transmission on a Bulk endpoint could make the driver stuck if the OUT endpoint was configured as a double buffer one.
- Driver could cause USB stack freeze in case of transfer timeout.
- Rx transfers with data size which is exact multiple of the endpoint packet size might have failed with DMA enabled.
- Transfers with data size which is exact multiple of the endpoint packet size might have failed with DMA enabled.
- Concurrent Bulk transfers could block each other.
- Slight modification of previous workaround which resulted in an unstable operation on heavy OUT traffic.
- A pending Bulk IN transfer could block all other Bulk transfers on higher pipes. Temporarily Bulk IN transfers are treated as INT ones.
- some transfers could stick in case of more parallel active transfers on different endpoints.
- fixed setting polling interval for interrupt endpoints.
- transfers were not started if there were >3 already active transfers.
- module renamed to usbh_hc_atmel (sources: usbh_atmel*, psp_usbh_atmel*).
- driver could freeze on device disconnection.
