Part Number: TDA2P-ABZ
Tool/software: Linux
Team,
Could you please answer my customer questions.
- I have some problem to distinguish which part of the whole TDA2Px system I can/have to configure through remoteproc and which part I can/have to configure directly in my code. Maybe you can give me some hints or further information.
- I found some Remoteproc example, where the PRU Interrupt Controller crossbar could be setup over the resource_table.h, like this :
TYPE_CUSTOM, TYPE_PRU_INTS,
sizeof(struct fw_rsc_custom_ints),
{ /* PRU_INTS version */
{
0x0000,
/* Channel-to-host mapping, 255 for unused
* Mapping Channel-1 to Host-1 (PRU0/1 R31 bit 31)
* */
{
HOST_UNUSED, 1, HOST_UNUSED, 3, HOST_UNUSED,
HOST_UNUSED, HOST_UNUSED, HOST_UNUSED, HOST_UNUSED, HOST_UNUSED
},
/* Number of evts being mapped to channels */
(sizeof(pru_intc_map) / sizeof(struct ch_map)),
/* Pointer to the structure containing mapped events */
pru_intc_map,
},
},
Is it possible to do a “resource_table.h”-configuration for the IRQ_CROSSBAR and the DMA_CROSSBAR of the TDA2Px system (A15,DSP,IPU)? I guess that I need some Remoteproc driver for the crossbars? If yes, where can I find the driver and can you send me an example how to do that?
- If it is not possible to configure crossbars through the resource table, my next question would be if there is a driver which I can use in my A15, IPU or DSP code?
Thank you.
- Needhu
