Other Parts Discussed in Thread: TDA4VM, TDA4VH
Dear ti,
we use the linux SDK 0805 version to test uboot fastboot function, buf found the issue:
after the uboot run "fastboot_handle_command : download:00008600", the usb dma index can't automatic increase the number “1”
we found the usb dma index is from the function：
static int cdns3_get_dma_pos(struct cdns3_device *priv_dev,
struct cdns3_endpoint *priv_ep)
{
int dma_index;
printf("%s ruijie :ep_traddr: 0x%x, readl(ep_traddr):0x%x trb_pool_dma:0x%x\n", __func__, priv_dev->regs->ep_traddr, readl(&priv_dev->regs->ep_traddr), priv_ep->trb_pool_dma);
dma_index = readl(&priv_dev->regs->ep_traddr) - priv_ep->trb_pool_dma;
return dma_index / TRB_SIZE;
}
we found the usb priv_dev->regs->ep_traddr can‘t automatic increase，
the log printf in TDA4VM ，it is normal log，
in line 2： cdns3_get_dma_pos ruijie :ep_traddr: 0xf7ec269c, readl(ep_traddr):0xf7ec269c trb_pool_dma:0xf7ec2600

but TDA4VH the ep_traddr value can't increase

we found the USB dev revision in TDA4VM is DEV_VER_TI_V1 , but in TDA4VH the usb version is DEV_VER_V3,
modify the TDA4VH use version to DEV_VER_TI_V1, the issue is fixed, can you help this? thanks
