- Move/make sure that ep0buf is in usb dma capable memory. Especially if .data/.bss are in TCM, the buffers need to be placed in another section. If the section .dmamemory doesn't exist, they will end up in .data like before - change "#ifdef CONFIG_ARCH_FAMILY_IMXRT117x" into "#if defined(CONFIG_ARCH_FAMILY_IMXRT117x) || defined(CONFIG_ARCH_FAMILY_IMXRT118x)" - In imxrt_epcomplete dtd->buffer0 must NOT be used to compute the data buffer's cache-maintenance address range. The hardware advances buffer0 (and its "current offset" low-order bits) as the transfer progresses, so by completion time it points *past* the start of the buffer (at start + xfer_len), not at the buffer itself. Instead, use the original privreq->req.buf when the transfer is complete. Signed-off-by: Jukka Laitinen <jukka.laitinen@tii.ae> |
