Hey rudi... um, I think I understand what you are saying...
You are wanting to solder a PSRAM to a PICO-D4 and play with Boris's MicroPython port this week if you have the time?
Hi Seon
yes you are right, this is the "master operation plan for monday"

let see whats happend, i search just in time the IPUS, Lyontek and a NoName pSRAM.
hope the wire plan is right and @espressif did nothing change in SIP, Board, BLOB BIN Library CODE (
I'm always very skeptical about that)
..I hope no one gets upset ..
ha ha
no problem - all @ESP_guys have now an "elephant skin",
did you read my "upset" posting to @espressif in the past
i am allways very explosive in this
the
psram theme has a very very emotional outbursts,
@q2222ch was very helpful in this by sending the first 3.3V pSRAM ( there was no 3.3V serial pSRAM on the market at this time )
so we could test the "magic 3.3V theme" too
before there where many
magic code to find out
... long story ..
look forward now.
Code: Select all
//psram gpio init , different working frequency we have different solutions
esp_err_t IRAM_ATTR psram_enable(psram_cache_mode_t mode, psram_vaddr_mode_t vaddrmode) //psram init
{
uint32_t chip_ver = REG_GET_FIELD(EFUSE_BLK0_RDATA3_REG, EFUSE_RD_CHIP_VER_PKG);
uint32_t pkg_ver = chip_ver & 0x7;
if (pkg_ver == EFUSE_RD_CHIP_VER_PKG_ESP32D2WDQ5) {
ESP_EARLY_LOGE(TAG, "ESP32D2WD do not support psram yet");
return ESP_FAIL;
} else if (pkg_ver == EFUSE_RD_CHIP_VER_PKG_ESP32PICOD2) {
ESP_EARLY_LOGE(TAG, "ESP32PICOD2 do not support psram yet");
return ESP_FAIL;
} else if (pkg_ver == EFUSE_RD_CHIP_VER_PKG_ESP32PICOD4) {
// ESP_EARLY_LOGE(TAG, "ESP32PICOD4 do not support psram yet");
ESP_EARLY_LOGE(TAG, "ESP32PICOD4 Nice to see this here now Yeah ;-)");
// return ESP_FAIL;
}
