Hi Aldo,
In the schematic, at the beginning I have the usb1 and usb2 configurated in that way.
I don't have any usb connector, but like I have, in another's projects it's work very well.
With that configuration, using UUU tool, In the terminal, the boot stops here:
U-Boot SPL 2020.04-00001-g62a81128c0-dirty (Feb 07 2023 - 15:50:55 +0000)
DDRINFO: start DRAM init
DDRINFO: DRAM rate 2400MTS
DDRINFO:ddrphy calibration done
DDRINFO: ddrmix config done
Normal Boot
Trying to boot from USB SDP
CRCN drivers/usb/imx/usb-mx6-common.c 303 val 3741319168 ctrl2 853803524
CRCN drivers/usb/gadget/ci_udc.c 960 4096 768
CRCN controller.epts is null
g_dnl_register: failed!, error: -12
SDP dnl register failed: -12
SPL: failed to boot from all boot devices
### ERROR ### Please RESET the board ###
In the function ci_udc_probe in ci_udc.c I have
static int ci_udc_probe(void)
{
struct ept_queue_head *head;
int i;
const int num = 2 * NUM_ENDPOINTS;
const int eplist_min_align = 4096;
const int eplist_align = roundup(eplist_min_align, ARCH_DMA_MINALIGN);
const int eplist_raw_sz = num * sizeof(struct ept_queue_head);
const int eplist_sz = roundup(eplist_raw_sz, ARCH_DMA_MINALIGN);
printf("CRCN %s %d %d %d\n",__FILE__,__LINE__,eplist_align,eplist_sz);
/* The QH list must be aligned to 4096 bytes. */
controller.epts = memalign(eplist_align, eplist_sz);
if (!controller.epts){
printf("CRCN controller.epts is null\n",__FILE__,__LINE__);
return -ENOMEM;
}
Then, I change the hardware, inserting the MIC2026, using only the A input/flag/output, and the result is the same.
As you can see, I put a printf ("CRCN controller.epts is null") if the result of the memalign is null.
Another test that I make, was configure USBNC_n_CTRL2 register (0x32E40204), to change DIG_ID_SEL to 1 (0xDF100000). Result is the same..
Why the boot stops here, in memalign? For me is strange that the USB part of the schematic is bad, if the Uboot SPL start run... Can be another problem regarding DDR, MMC, etc???
Regarding your question about uboot version, I'm using uboot 2020.04.
Thanks.
