History: nw_drv_eth_etna

This page describes all changes made to the nw_drv_eth_etna package, Network Driver for Renesas RH850, since its release.


1.5 (2021-04-20, 18:00):

  • Updated to work with nw_drv_base v5.6.
  • Warnings removed.

1.4r2 (2021-03-08, 10:25)

  • Fixed PSP RH850 psp_isr_delete() function to set the return value to success when the isr_id is correct.

1.4 (2021-03-04, 14:20)

  • Fixed the issue that meant ethdriver_etna_init() returned the same t_nwdriver structure for both ports so port0 data was overwritten with port1 data during start.

1.3 (2021-03-02, 18:00)

  • Fixed version file include path.
  • Removed interrupt disable/enable from add_buf/receive/send function, because all the changes made in the DMA descriptors and property data are done before the descriptors are passed to the DMA engine.
  • Fixed pin configuration in PSP RH850. Drive strength was not correctly set for all output pins which resulted in untransmitted frames.

1.2 (2021-02-03, 15:00):

  • Added support for two Ethernet ports.
  • Introduced core and PHY loopback modes.
  • Connected state reported faster (PHY speed and duplex mode is set during the start of the driver instead of setting them always after PHY reports a newly connected state).
  • Removed "HCC_" prefix from configuration option names.


  • Initial release.
