This is now tested to work; I will wait for upstream review before merging |
…UGASSERTS Correct some of the cache operations: - EP0 request length was handled incorrectly - Received data cache invalidate was exceeding the received buffer - writedtd is also called with no data (EP0 ACK/NACK). Don't touch cache in that case. Fix trip wire handling to conform with the IMX93 reference manual Also add DEBUGASSERTS for future to check the validity of pointers and sizes Co-authored-by: Jukka Laitinen <[email protected]>
…ep->maxpacket and CONFIG_CDCACM_BULKIN_REQLEN The request length may not exceed CONFIG_CDCACM_BULKIN_REQLEN, otherwise buffer overflow will occur This part is already changed in upstream with a slightly different patch Signed-off-by: Jukka Laitinen <[email protected]>
… exceed CONFIG_PL2303_BULKIN_REQLEN The request length may not exceed CONFIG_PL2303_BULKIN_REQLEN, otherwise buffer overflow will occur Signed-off-by: Jukka Laitinen <[email protected]>
