Hi team,
I transplanted u-boot based on AM64 SDK9.0 with reference to AM65 SDK8.6.
I found there are no ICSSG related driver files found in AM64 SDK9.0 ti-u-boot/drivers/net/ti , I copied them from the AM65 SDK folder.
I'm stuck on icssg_config() function in prueth_probe() function, located in ti-u-boot/drivers/net/ti/icssg_prueth.c
There is only one last step left to successfully probe.
static int prueth_probe(struct udevice *dev){
/* Set Load time configuration */
…
icssg_config(prueth);
}
ti-u-boot/drivers/net/ti/icssg_config.c:
int icssg_config(struct prueth *prueth){
…
icssg_config_rgmii_init(prueth, slice);
icssg_config_mii_init(prueth, slice);
…
}
ti-u-boot/drivers/net/ti/icssg_config.c:
static void icssg_config_rgmii_init(struct prueth *prueth, int slice){
…
regmap_write(miig_rt, ICSSG_CFG_OFFSET, ICSSG_CFG_DEFAULT | mii_mode);
…
}
ti-u-boot/drivers/core/regmap.c:
int regmap_write(struct regmap *map, uint offset, uint val){
…
printf("regmap_write, offset:%x\n", offset);
printf("regmap_write, val:%x\n", val);
printf("map->width:%d\n", map->width); //I don’t understand why get the map->width value, can cause "Synchronous Abort" handler, esr 0x96000004
switch (map->width) {
case REGMAP_SIZE_8:
..
}
UART Output error part:
regmap_write, offset:0
regmap_write, val:1082f
