Tool/software:
For the .base section in this Ipc_ResourceTable in ti/drv/lpm/src/lpm_ipc_rsctable.h, it seems that .num is being set to the version number, and .ver is being set to the number of entries. I tried using this resource table in my own program and it crashed. I had to correct this problem as shown below. I was using ti-processor-sdk-rtos-j721e-evm-10_00_00_05/pdk_jacinto_10_00_00_27.
const Ipc_ResourceTable ti_ipc_remoteproc_ResourceTable __attribute__ ((section (".resource_table"), aligned (4096))) =
{
// I FOUND A BUG!
// SHOULD BE
// .base =
// {
// .num = NUM_ENTRIES, /* number of entries in the table */
// .ver = 1U, /* we're the first version that implements this */
// .reserved = {0U, 0U}, /* reserved, must be zero */
// },
// CURRENTLY WE HAVE THIS
.base =
{
.num = 1U, /* we're the first version that implements this */
.ver = NUM_ENTRIES, /* number of entries in the table */
.reserved = {0U, 0U}, /* reserved, must be zero */
},
/* offsets to entries */
.offset =
{
offsetof(Ipc_ResourceTable, rpmsg_vdev),
offsetof(Ipc_ResourceTable, trace),
},
/* rpmsg vdev entry */
.rpmsg_vdev =
{
TYPE_VDEV, VIRTIO_ID_RPMSG, 0U,
RPMSG_R5F_C0_FEATURES, 0U, 0U, 0U, 2U, { 0U, 0U },
/* no config data */
},
/* the two vrings */
.rpmsg_vring0 =
{ RPMSG_VRING_ADDR_ANY, 4096U, R5F_RPMSG_VQ0_SIZE, 1U, 0U },
.rpmsg_vring1 =
{ RPMSG_VRING_ADDR_ANY, 4096U, R5F_RPMSG_VQ1_SIZE, 2U, 0U },
.trace =
{
(TRACE_INTS_VER0 | TYPE_TRACE), TRACEBUFADDR, IPC_TRACE_BUFFER_MAX_SIZE, 0, "trace:r5f0",
},
};
The problem in seen here on lines 81 and 82

Also is this the correct way to report a bug? How should I report problems I find to TI?
