Flash erase/write/read test failing

[iosixllc]

I am running the following code, to perform a regression test on the flash memory, and am getting a lot of errors. Note that before, when we were running VSDIO @ 3.3V (D2WD), the flash was working perfectly. Once we set the fuse for 1.8V, these errors started, and I'm sorry to say we are still seeing the errors on our new boards with the correct strapping configuration for 1.8V pre-installed. I'm set to DIO and 40MHz SPI speed. These errors also occur during OTA update; log at bottom.

#define F_SECTORSIZE 0x1000
#define F_MEMSIZE 0xF0000
#define F_SEGMENTSIZE 32

void rtest_cmdfunc (char * outstr, u16 maxlen) {
esp_partition_t * OtaPartition = 0;
u16 p, q;
OtaPartition = esp_ota_get_next_update_partition(NULL);

// erase and then verify erased
rbt_erase(OtaPartition, 0, F_MEMSIZE);
for (q = 0; q < F_SECTORCOUNT; q++) {
rbt_read(OtaPartition, q * F_SECTORSIZE, FLASHBUFFER, F_SECTORSIZE);
u16 isnotff = 0;
for (p = 0; p < F_SECTORSIZE; p++) {
if (FLASHBUFFER[p] != 0xFF)
isnotff++;
}
if (isnotff) {
debug_printf("ERASE SECTOR ERROR: %u, %u not FF\n", q, isnotff);
}
}

// write pattern shifted

for (p = 0; p < F_SECTORSIZE; p++)

RESETTING

[iosixllc]

Also - is there a way I can disable caching of read/write operations to flash or do the partition read/write functions bypass caching?

[WiFive]

rbt_write does a verify which passes on a segment but the subsequent verify on a sector fails? And always the first segment of the sector?

[iosixllc]

Seems so from this log, yes.
